Information for all Attendees – <strong>IEEE</strong> <strong>Transformers</strong> <strong>Committee</strong> Meeting, Spring ‘09<br />

<strong>IEEE</strong> Patent Requirements for Standards Development Meetings<br />

As discussed during the last several years, the <strong>Committee</strong> continues to be aware of <strong>IEEE</strong><br />

requirements related to the possibility of inclusion of patents in <strong>IEEE</strong> Standards. The instances are<br />

expected to be rare, and subject to specific review and guidelines. Detailed information on this subject<br />

can be found in <strong>IEEE</strong> website locations listed below. Of present concern to <strong>Committee</strong> work is the<br />

requirement that, at every standards development meeting, a request be made for disclosure of any<br />

patents or patent applications any individual believes may be essential to the implementation of the<br />

standard. The request, per present <strong>IEEE</strong> guidelines, is to be made at each WG Meeting, and any<br />

responses provided are to be recorded in Meeting Minutes. Positive responses will also prompt a request<br />

for documentation on the patent to be supplied to <strong>IEEE</strong>.<br />

<strong>IEEE</strong> Instructions for WG Chairs are found on the following Instructions and 4 slides, available at<br />

<strong>IEEE</strong> web location (http://standards.ieee.<strong>org</strong>/board/pat/pat-slideset.ppt)<br />

Our WG Meetings are relatively short, and taking the time show all the slides associated with the<br />

required “call” for patents presents a hardship in our schedule. In order to minimize the impact on WG<br />

Meetings, while meeting the intent of the <strong>IEEE</strong> guidelines, these notes and slides are being provided on<br />

the <strong>Committee</strong>’s website, and all meeting participants are encouraged to review prior to the meeting.<br />

With this preparation the announcement at WG Meetings, per the following slides, should take no more<br />

than a few minutes – and the <strong>Committee</strong> judges that showing of each slide at each WG Meeting, while<br />

appropriate if requested, is not necessary. For any questions, refer to the following websites, or contact<br />

one of the <strong>Committee</strong> officers.<br />

• (http://standards.ieee.<strong>org</strong>/guides/bylaws/sect6-7.html#6) – Note Clause 6 - Patents<br />

Instructions for the WG Chair<br />

Bill Chiu<br />

Secretary<br />

The <strong>IEEE</strong>-SA strongly recommends that at each WG meeting the chair or a<br />

designee:<br />

� Show slides #1 through #4 of this presentation<br />

� Advise the WG attendees that:<br />

� The <strong>IEEE</strong>’s patent policy is consistent with the ANSI patent policy and is described in Clause 6<br />

of the <strong>IEEE</strong>-SA Standards Board Bylaws;<br />

� Early identification of patent claims which may be essential for the use of standards under<br />

development is strongly encouraged;<br />

� There may be Essential Patent Claims of which the <strong>IEEE</strong> is not aware. Additionally, neither the<br />

<strong>IEEE</strong>, the WG, nor the WG chair can ensure the accuracy or completeness of any assurance<br />

or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the<br />

standard under development.<br />

� Instruct the WG Secretary to record in the minutes of the relevant WG meeting:<br />

� That the foregoing information was provided and that slides 1 through 4 (and this slide 0, if<br />

applicable) were shown;<br />

� That the chair or designee provided an opportunity for participants to identify patent<br />

claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application<br />

claim(s) of which the participant is personally aware and that may be essential for the use of<br />

that standard<br />

� Any responses that were given, specifically the patent claim(s)/patent application claim(s)<br />

and/or the holder of the patent claim(s)/patent application claim(s) that were identified (if any)<br />

and by whom.<br />

� The WG Chair shall ensure that a request is made to any identified holders of potential essential<br />

patent claim(s) to complete and submit a Letter of Assurance.<br />

� It is recommended that the WG chair review the guidance in <strong>IEEE</strong>-SA Standards Board Operations<br />

Manual 6.3.5 and in FAQs 12 and 12a on inclusion of potential Essential Patent Claims by<br />

incorporation or by reference.<br />

Note: WG includes Working Groups, Task Groups, and other standards-developing committees with a PAR<br />

approved by the <strong>IEEE</strong>-SA Standards Board.<br />

Participants, Patents, and Duty to Inform<br />

All participants in this meeting have certain obligations under the <strong>IEEE</strong>-SA<br />

Patent Policy. Participants:<br />

� “Shall inform the <strong>IEEE</strong> (or cause the <strong>IEEE</strong> to be informed)” of the identity of<br />

each “holder of any potential Essential Patent Claims of which they are<br />

personally aware” if the claims are owned or controlled by the participant or<br />

the entity the participant is from, employed by, or otherwise represents<br />

� “Personal awareness” means that the participant “is personally aware that the<br />

holder may have a potential Essential Patent Claim,” even if the participant is not<br />

personally aware of the specific patents or patent claims<br />

� “Should inform the <strong>IEEE</strong> (or cause the <strong>IEEE</strong> to be informed)” of the identity<br />

of “any other holders of such potential Essential Patent Claims” (that is,<br />

third parties that are not affiliated with the participant, with the participant’s<br />

employer, or with anyone else that the participant is from or otherwise<br />

represents)<br />

� The above does not apply if the patent claim is already the subject of an<br />

Accepted Letter of Assurance that applies to the proposed standard(s)<br />

under consideration by this group<br />

Quoted text excerpted from <strong>IEEE</strong>-SA Standards Board Bylaws subclause 6.2<br />

� Early identification of holders of potential Essential Patent Claims is strongly<br />

encouraged<br />

� No duty to perform a patent search<br />

CHAIR’S REPORT – SPRING ‘09 – MIAMI, FLORIDA<br />

1.0 Chair’s Report – T. A. Prevost<br />

1.1 <strong>PES</strong> General Meeting Notes<br />

The last <strong>PES</strong> General Meeting was held in Pittsburgh, PA this summer from July 20-24.<br />

The schedule for upcoming <strong>PES</strong> General Meetings is as follows:<br />

• 2009: July 26-30 in Calgary, Alberta, Canada<br />

<strong>PES</strong> Conference & Exposition (CE) schedules:<br />

• 2009: Power Systems (PSCE), March 15-18 in Seattle, Washington<br />

Additional information on any of the above meetings can be found on the <strong>PES</strong> website at<br />

(http://www.ieee.<strong>org</strong>/portal/site/pes/)<br />

1.2 <strong>PES</strong> Technical Council Activities<br />

Because the <strong>PES</strong> only meets once per year the Technical Council now has instituted<br />

monthly conference calls to cover key topics. A summary of key issues follows:<br />

1.2.1 O&P Manual<br />

<strong>PES</strong> has submitted a revised O&P manual to <strong>IEEE</strong> Audcom. This O&P covers the<br />

technical activities of <strong>PES</strong> but does not cover the standards development activities. The<br />

technical council O&P committee has decided to delegate the standards development<br />

O&P to those technical committees which sponsor standards development activities. This<br />

will require the <strong>Transformers</strong> <strong>Committee</strong> to comply with the <strong>IEEE</strong> SA template for<br />

standards developing committees and for the <strong>Transformers</strong> <strong>Committee</strong> to have their O&P<br />

approved directly by Audcom.<br />

1.2.2 2008 General Meeting in Pittsburgh<br />

The meeting was very successful with over 2,200 attendees, which is a record.<br />

1.2.3 <strong>PES</strong> TC Planning Meeting<br />

A planning meeting has been coordinated for all technical committees in Pes regarding<br />

the future of <strong>PES</strong> activities. This will be a two day facilitated meeting including<br />

representation from each technical committee within <strong>PES</strong>. Tom Prevost represented the<br />

transformers committee. The meeting is scheduled for September 27 –29, 2008. A verbal<br />

update will be given at the adcom meeting in Porto.<br />

1.2.4 Standards Coordination<br />

Standards coordination among the different committees continues to be a concern since<br />

the advent of the electronic standards process. The role of the standards coordinator has<br />

attained greater importance as a result. Bill Bartley should be made aware of any scope<br />

conflicts or coordination issues between the Transformer and other technical committees<br />

of <strong>PES</strong>.<br />

1.2.5 125 th Anniversary of <strong>PES</strong><br />

Next year, 2009, will be the 125 th anniversary of the Power and Energy Society. Stay<br />

tuned for events to commemorate this milestone.<br />

1.3 <strong>Transformers</strong> <strong>Committee</strong> Activities<br />

Progress since last meeting in several areas of concern for the <strong>Committee</strong>, together with<br />

notes of <strong>Committee</strong> interest, follow:<br />

1.3.1 C57 Standards CD<br />

A CD of all of the transformer standards is still available from <strong>IEEE</strong>. I would again like<br />

to thank Bill Bartley, Greg Anderson and Bill Chiu as well as Matt Ceglia, our <strong>IEEE</strong><br />

Staff Liaison for their efforts in producing this collection and making it available.<br />

1.3.2 <strong>Committee</strong> Membership<br />

All are welcome to participate in the work of the <strong>Transformers</strong> <strong>Committee</strong>. Membership<br />

in the <strong>Committee</strong> provides recognition of your peers and indication to your co-workers<br />

and management of your active role in <strong>Committee</strong> work. If you are presently not a Main<br />

<strong>Committee</strong> Member, and you have been actively participating in our work for at least one<br />

full year – and can secure the acknowledgement of at least 3 Activity Chairs (WG’s, but<br />

must include at least one SC Chair) affirming that participation, the <strong>Committee</strong> will look<br />

forward to welcoming you as a member. Membership requirements and application<br />

forms can be found in the Organization and Procedures Manual posted on the <strong>Committee</strong><br />

website.<br />

1.3.3 Association Management (AM) System<br />

All <strong>Committee</strong> members and active participants, and all individuals interested in<br />

<strong>Transformers</strong> <strong>Committee</strong> activities, are reminded that virtually all communications on<br />

<strong>Committee</strong> meetings and activities are handled through the <strong>Committee</strong> website<br />

(http://www.transformerscommittee.<strong>org</strong>/) and through electronic media. Contact<br />

information is maintained through our Association Management (AM) system, and<br />

administration of membership and meeting attendance records is facilitated by the AM<br />

System. All Subcommittee and Working Group Chairs are encouraged to use the AM<br />

system for assigning membership within their groups and for communication with their<br />

group members. All <strong>Committee</strong> members, active participants, and interested individuals<br />

are reminded also that you are responsible personally for maintaining the accuracy of<br />

your contact information, through the AM system, for <strong>Committee</strong> activities and<br />

communication. Updating your contact information in handwriting on a meeting roster<br />

does not result in updating your <strong>Committee</strong> contact information. Keeping your contact<br />

information maintained in the AM system assures that the Chair of any Subcommittee or<br />

Working Group you are involved with will be able to communicate with you. Details on<br />

enrolling and maintaining your contact information in the AM system can be found on<br />

the <strong>Committee</strong> website.<br />

2.0 Approval of Minutes from Fall, 2008 Meeting<br />

Chair asked that a motion be made to approve the minutes of the Fall, 2008 (Porto,<br />

Portugal) meeting. A motion was made and seconded from the floor. The Chair asked<br />

for a voice vote, which was unanimously approved. The Chair declares the Fall, 2008<br />

Porto minutes approved as written with a correction noted during the meetings leading up<br />

to the main committee meeting on April 23, 2009. 1<br />

1 Note – prior to the main meeting, <strong>Committee</strong> Secretary received a request to change the unapproved<br />

minutes from the Distribution <strong>Transformers</strong> Subcommittee due to the lack of a quorum that rendered a vote<br />

on a motion to be invalid. This was also discussed at the Administrative Subcommittee on Sunday, April<br />

19, 2009. These changes were incorporated in the final “Approved” version for the Fall, 2008 meeting.<br />

3.4 Meeting Arrangements, Host Report, and <strong>Committee</strong> Finances<br />

G. Anderson circulated a list of people who has administrative access to AMS-123 system. All<br />

in attendance were asked to verify the list and make<br />

3.4.1 Meetings/Finances – G. W. Anderson (:10)<br />

<strong>Committee</strong> funds:<br />

Before Porto meeting the committee has available funding of approximately $28,000 ($28,030).<br />

Before the Charlotte meeting, the committee has available funding of approximately $47,000.<br />

Before the Minneapolis meeting, the committee has available funding of approximately $44,000.<br />

The Charlotte meeting took a hit financially, due in part to the expenses at Charlotte. Overall, G.<br />

Anderson felt while we are down about $19,000 from before the Charlotte meeting, our financial situation<br />

is still in good standing.<br />

Future meeting time slots and locations:<br />

F09 (October 25-29, 2009) – Lombard, IL (suburbs of Chicago) at the Westin Lombard Hotel. Room rate<br />

is $149 per night + tax. The hotel is only two years old. There will be a technical tour of the S&C new<br />

High Power Laboratory.<br />

S10 (March 7-11, 2010) – Location TDB. Will be in the warm part of the country.<br />

The membership status has been updated in the AMS123 system and each new member should<br />

have received a notification of this change.<br />

The <strong>Committee</strong> currently has three general categories of participation in our activities. These are:<br />

Interested Individual, Active Participant, and <strong>Committee</strong> Member. Any one can join our AMS<br />

123 system as the system is designed for self-registration. A new participant will automatically be<br />

assigned the role of Interested Individual when they first sign up.<br />

Based on the level of participation, the committee administrative staff will upgrade the<br />

participation status to “Active Participant” when appropriate. Currently an “Active Participant” is<br />

some one who attends at least three out of the past 5 meetings and actively contributed to the<br />

work of the <strong>Committee</strong>.<br />

The <strong>Committee</strong> Member status however, can only be attained through a formal application with<br />

the sponsorship of minimum of three WG or SC chairmanships. Detail of the application<br />

requirement and approval process by the Administrative Subcommittee is outline in our O&P<br />

manual.<br />

The participant’s profiles in our AMS 123 system should reflect the correct status. Here is the link<br />

These applications will be reviewed at the Administrative Subcommittee meeting. The <strong>Committee</strong><br />

welcomes and encourages active participants to become Members of the <strong>Committee</strong>.<br />

Requirements and application forms can be found in the Organization and Procedures (O&P)<br />

Manual, accessible on the <strong>Committee</strong> website. Subcommittee Chairs are encouraged to<br />

recommend new members, and also to increase the awareness that Membership is a privilege<br />

gained through active participation and contribution in <strong>Committee</strong> work at the WG and SC<br />

level. WG and SC Chairs are reminded also that signing an application sponsoring a new<br />

member signifies their sponsorship that the applicant has met the requirement of membership<br />

and active participation for at least one year in the WG or SC they Chair. New member<br />

applications should be submitted to the <strong>Committee</strong> Secretary’s attention at any time. Application<br />

will be collected for review and approval in batches at each Administrative Subcommittee<br />

meeting. For an application to be included in the following meeting, the application will need to<br />

be received by the <strong>Committee</strong> Secretary at a minimum of one week prior to the start of the next<br />

meeting.<br />

3.10.3 <strong>Committee</strong>, Subcommittees, and Working Group Rosters<br />

In order to provide indemnification to working group and subcommittee members it is crucial that<br />

membership lists be maintained. Our AM system has these functions built-in to ease these<br />

administration tasks. It is important that each subcommittee and working group chair keep the<br />

rosters updated so that this information can be provided to the <strong>IEEE</strong> SA.<br />

A similar main committee roster has also been developed to track attendance for the Main<br />

<strong>Committee</strong> meeting on Thursdays. The data will be used to update participant’s membership<br />

profile.<br />

3.10.4 Meeting Minutes<br />

The minutes of the Porto, Portugal, Fall 2008 <strong>Transformers</strong> <strong>Committee</strong> meeting were posted to the<br />

committee website on Wednesday, April 1, 2009.<br />

Meeting minutes are now only available via electronic means. A collection of recent meeting minutes are<br />

available in pdf format from the committee’s website.<br />

Subcommittee Chairs are requested to submit their SC Minutes for the Miami meeting by June 30, 2009.<br />

Minutes should be submitted via e-mail to the Secretary bill.chiu@ieee.<strong>org</strong> , with a copy to Susan McNelly<br />

sjmcnelly@ieee.<strong>org</strong> for posting on the <strong>Committee</strong> website. The submittal should be formatted in Word<br />

2007 (or earlier versions) and should be formatted in the format as shown in the present assembled<br />

Minutes, with numbering as indicated in Main <strong>Committee</strong> Meeting Agenda. Please indicate total<br />

attendance count for each Subcommittee, Working Group, and Task Force meeting in your Minutes.<br />

Please do not send a copy of the attendance listing for this attendance count. If a SC Vice-Chair,<br />

Secretary, or other SC member is preparing the SC Minutes, please let them know these details about<br />

Minutes submittals.<br />

Please do all you can to get the minutes in as soon as possible. Collecting the minutes from each<br />

subcommittee is the most difficult and time consuming part of this job and I would very much appreciate<br />

your help in facilitating the compilation of the combined minutes. Your attention to this matter is greatly<br />

appreciated.<br />

3.8 Standards Report – B. Bartley<br />

Refer to Standards Report on activity since the October, 2008 Meeting (Porto, Portugal) published in the<br />

Main Meeting Minutes.<br />

Attention was call to the list of projects where PARS that have not started the balloting process and will<br />

be expiring at the end of 2009. The responsible Subcommittee chairs are requested to coordinate with<br />

each of the Working Group Chair to take appropriate actions prior to the deadline in October 19, 2009.<br />

Bill Bartley also offered to work with the activity chair to take the appropriate actions.<br />

The Standards Report is included in the Appendix C - Transformer Standards Development Status and<br />

Transformer <strong>Committee</strong> Organizational Chart.<br />

3.9 New Business<br />

3.9.1 DOE Voluntary Compliance Sticker for Distribution <strong>Transformers</strong><br />

Stephen Shull mentioned the Distribution <strong>Transformers</strong> Subcommittee is working on developing a<br />

labeling standard (such as a sticker) to indicate compliance with the DOE efficiency requirements.<br />

Minutes of the Distribution SC from the Porto meeting has a summary of the discussion. Due to lack of<br />

quorum, the vote on the motions was deemed invalid and the minutes from the F’08 meeting will be<br />

updated to reflect a “recommendation” in place of a “motion.”<br />

This recommended labeling would mean the existing standards such as C57.12.00 and the C57.12.37 will<br />

need to coordinated to reflect this new labeling requirement. Further discussion will take place at the<br />

Distribution <strong>Transformers</strong> SC.<br />

3.9.2 New Style Guide – Peter Balma<br />

Peter Balma presented several items of interests on the new style guide for writing the standards:<br />

1. Introduction Section – this is a good place to include a brief history of the document<br />

2. Notes on tables are informative; not normative<br />

3.9.3 History of the <strong>IEEE</strong> TC – Peter Balma<br />

Peter Balma also presented a brief discussion on the need to document the history of the <strong>Transformers</strong><br />

<strong>Committee</strong>. Peter sought permission from the AdComSub to allow him to work with <strong>IEEE</strong> to develop a<br />

history of the <strong>Committee</strong>. Permission was granted by the AdComSub with no objection nor discussion.<br />

Peter will report back to the AdSubCom with progress updates.<br />

3.10 <strong>Committee</strong> Service Awards – D. Fallon<br />

Refer to Section 6.0 for the complete “Recognition and Awards Report.”<br />

3.11 Subcommittee Reports<br />

3.11.1 Greg Anderson - Meetings Subcommittee<br />

NO REPORT<br />

3.11.2 Thang Hochanh (for Loren Wagner) - Dielectric Test Subcommittee<br />

Thang Hochanh will be the acting chair for the Dielectric Tests SC for this meeting. Thang Hochanh also<br />

indicated the Dielectric Test Subcommittee is sponsoring a tutorial on Analysis of Transformer<br />

Characteristics Through Frequency Response Analysis” on Monday afternoon.<br />

3.11.3 Tom Lundquist - Power Transformer Subcommittee<br />

Tom Lunquist raised a point of discussion to seek clarification on membership application to the<br />

subcommittees. After some discussion it was confirmed that the Chair of the Subcommittee or the<br />

Working Group has the authority to determine if there is a need to add additional members to the group.<br />

This is particularly a point of contention especially when the majority of the work has already been<br />

completed and new applicant is really not in a position to take on the role of an active contributor. In such<br />

situation, the Chair should exercise his or her own judgment on whether to accept the new membership<br />

request.<br />

3.11.4 Peter Zhao (for Fred Elliott) - Bushings Subcommittee<br />

Peter Zhao brought forth a dual logo potential for IEC 62199 and PC57.19.03 (bushings for DC<br />

application). There is support from the IEC <strong>org</strong>anization to proceed as a Dual Logo development effort.<br />

One of the potential area of concern would be the formality of references. The PAR as submitted was not<br />

checked as a dual logo potential. The <strong>Committee</strong> will engage <strong>IEEE</strong> staff to start a conversation on<br />

developing a join working group guideline for a dual logo document.<br />

3.11.5 Richard Dudley - HVDC Converter <strong>Transformers</strong> & Reactors Subcommittee<br />

Richard Dudley raised a question on whether or not the Chair of a Working Group has the authority to<br />

exclude new subjects being brought forth to the working group, especially of the document is already well<br />

on its way towards completion. The Chair of the <strong>Committee</strong> added the Chair of the Working Group has<br />

the call, but the issue must be vetted through the working group members.<br />

3.11.6 Stephen Shull (for Ken Hanus) - Distribution Transformer Subcommittee<br />

See the New Business section regarding the DOE compliance sticker discussion. No additional report.<br />

3.11.7 Richard Ladroga (Sue McNelly) - Insulation Fluids Subcommittee<br />

Richard Ladroga reported that a new TF is being formed to evaluate a need for a field application of<br />

Natural Esters. Richard also thanked the many volunteers to push the C57.104 document through the<br />

balloting process.<br />

3.11.8 Jeewan Puri - Audible Sound and Vibration Subcommittee<br />

NO REPORT<br />

3.11.9 Don Platts - Insulation Life Subcommittee<br />

Don Platts reported that Tim Raymond has resigned as the WG Chair for PC57.91. Don Platts will step-in<br />

to chair the PC57.91 working group until such time as a new working group chair has been selected.<br />

3.11.10 Steve Antosz (for Ramsis Girgis) - Performance Characteristics Subcommittee<br />

NO REPORT<br />

3.11.11 Dan Mulkey (for Carl Niemann) - Underground Transformer & Network Protector<br />

3.11.12 Charles Johnson - Dry Type Transformer Subcommittee<br />

Chuck Johnson reported that the John Sullivan, Chair for the C57.12.01 working group, has resigned his<br />

role as the Working Group chair and Tim Holdway will be taking over the role of chairman.<br />

3.11.13 Jim Smith (Ross McTaggart) - Instrument Transformer Subcommittee<br />

NO REPORT<br />

3.12 OLD Business – O&P Manual<br />

The Chair starts by thanking Pete Balma for his significant contributions to the revision of the O&P<br />

Manual. Feedbacks from the AdSubCom members were compiled and discussed. Two key issues up for<br />

discussion were:<br />

Administrative Subcommittee Meeting<br />

Miami, Florida<br />

April 19, 2009<br />

1. Working Group PAR approval requirement<br />

The key change in this area is the clarification of requirement that PARs will need to be<br />

approved by the AdSubCom prior to being submitted to <strong>IEEE</strong>. Conflicts, if any, will be<br />

resolved between the Standards Coordinator, the Main <strong>Committee</strong> Chair, and the Chair of the<br />

sponsoring subcommittee.<br />

2. <strong>Committee</strong> membership requirements<br />

The key change in this area is the duration of the apprenticeship requirement from one year to<br />

two year.<br />

The revised O&P Manual will be submitted to <strong>IEEE</strong>/<strong>PES</strong> for approval and will be made available by<br />

posting them to our website once approval has been obtained.<br />

The <strong>Committee</strong> Chair stated this is not the end of the O&P Manual revision. The O&P manual will need<br />

to be expanded to the Working Group level in the future.<br />

3.13 Adjournment<br />

Summary: Natural ester seed oil based dielectric fluid is an environmentally advantaged<br />

fluid that is increasingly being used as a replacement for mineral oil and for high<br />

temperature flashpoint liquids, including silicone and R-TEMP. This report updates<br />

experience with use of the fluid over the last two years. Considerable studies have been<br />

conducted to investigate heat aging performance of cellulose, electrical contact thermal<br />

stability, dielectric strength, moisture sensitivity, and cold temperature performance. A<br />

Standards Subcommittee Meeting<br />

April 22, 2009 Hilton Hotel, Miami Florida, USA<br />

5.0 Standards Subcommittee Meeting – B. Bartley, Chair<br />

5.1 Opening Remarks<br />

a) Chair, William Bartley summarized the recent activities at the RevCom meeting that resulted in the<br />

readiness for issuance of <strong>Transformers</strong> <strong>Committee</strong> Organization & Procedures Manual – April 2009.<br />

The O&P Manual was posted on TC website the following week. (Postscript - link is<br />

www.transformerscommittee.<strong>org</strong>/info/OPMan04-2009.pdf).<br />

b) The Spring 2009 Standards Report website location shown with explanation that it would be presented in<br />

detail at the April 23 main meeting. (The link is;<br />

http://www.transformerscommittee.<strong>org</strong>/meetings/S2009_Miami/Minutes/S09-StdsReport.pdf )<br />

c) The Chair reported from ADCOM meeting, there is a new requirement for documenting comments<br />

resolution. This pertains to requirement of “evidence of consideration” that shall provide a means for all<br />

comment to be documented, as well as the resolution. Use the comment resolution feature.<br />

d) There is also a new 2009 <strong>IEEE</strong> Style Manual, and everyone that is starting a new Working Group is<br />

encouraged to use the 2009 <strong>IEEE</strong> Style Manual. You will find the link in the Spring 2009 Standards<br />

Report noted above, or may go directly to new “2009 <strong>IEEE</strong> Standards Style Manual” on <strong>IEEE</strong> Standards<br />

website at the following URLs: http://standards.ieee.<strong>org</strong>/guides/style/2009_Style_Manual.pdf<br />

5.2 Meeting Attendance<br />

The Standards Subcommittee met on Wednesday, April 22, 2009, at 4:30 PM. A count of members request to<br />

stand if believed to be members showed 17 members in attendance. (Noted as not enough for a quorum; however,<br />

business as usual was conducted). The meeting roster was circulated.<br />

5.3 Approval of previous meeting minutes<br />

Vice Chair motioned for approval of the previous meeting minutes. The meeting minutes from the Fall 2008<br />

meeting in Proto, Portugal were approved as written.<br />

5.4 Working group reports.<br />

a) Cont. Revision of C57.12.00 – Bill Bartley provided the initial ballot results as; 129 affirmed, 15<br />

negative with comments, and 16 abstained. The present status is that ballot resolution is complete and<br />

that standard would go back out for re-balloting.<br />

b) Cont. Revision of C57.12.90-2006 – S. Antosz- The jointly timed ballot of C57.12.00 and C57.12.90<br />

results for C57.12.90 from Oct 2008, were a total of 26 ballots, with 7 negatives and 109 comments. The<br />

comments and resolution were documented, per the evidence of consideration, and a recirculation was<br />

held on March 6, 2009 resulting in 3 of the previous negatives changing to approved and 4 not<br />

responding. Therefore, after consulting with the appropriate Subcommittees there is nothing holding the<br />

publication of C57.12.90. However there was one new strong negative that will be discussed in this<br />

meeting. In this case the Chairman is actually a working group of one, and there are not working group<br />

meetings per se. This meeting was used to discuss the issue point of when a seller should notify the buyer<br />

when the manufacturer can not meet the rise time for full wave impulse (dielectric, session 10.3.1.1).<br />

The issue is: Should it be at time of bid (which would be the buyer preference); or should it be after the<br />

electrical design, when the manufacturer actually knows the design versus the test equipment capability.<br />

Following a discussion on both rise time and tail time, many opinions were provided, but no clear<br />

consensus was reached. The issue will be taken to the Dielectric Test Subcommittee, as an open action<br />

by Chair (S. Antosz).<br />

c) PC57.12.70 Terminal Markings Revision – S. Shull – The goal is to bring much of the IEC<br />

nomenclature regarding terminal markings into the <strong>IEEE</strong> document. Much work has been done to date,<br />

and there the research being performed to determine if the IEC figures can be brought into the document.<br />

Progress continues.<br />

d) WG on Revision of <strong>IEEE</strong> C57.152 (old 62) –Jane Verner – Draft 3 of PC57.152 is posted on the<br />

website. Three web meetings were held since Porto. We are estimating the document is at 80%<br />

completion with thirty sections submitted and reviewed. At the March 26 web meeting a limit of an<br />

acceptable power factor in the guide was discussed. Follow up research on typical power factor for<br />

rectangular core construction limits on new units was made. Further discussion took place in Miami with<br />

one suggestion that if the limits were included the guide may be in conflict with C57.12.90. The Factory<br />

Test standard is different than the Field Guide and there was much debate. In the end a vote strongly<br />

favored the inclusion of a power factor limit as this is a Guide and many users especially smaller utilities<br />

and municipals, need some basis for an indication of a further investigation or not. Often records of<br />

factory testing are not available. The Guide will also include a statement to review the change in power<br />

factor over the life of the unit.<br />

e) PC57.12.80 – Terminology for P & D <strong>Transformers</strong> – B. Chiu The document went to ballot in<br />

March 2009, and presently is going through comment resolution. Upon comment resolution the<br />

PC57.12.80 will go out for recirculation. The members were recognized for their cyber space<br />

contributions (no formal meeting held). The ballot had 97% response with only 3 negative ballots. There<br />

were over 100comments many editorial. The key areas normative versus informative, IEC being a<br />

normative – will be moved to informative. Look for recirculation in about 10 days, and then it will go to<br />

RevCom. See the attached PowerPoint slides for the status update given by Bill Chiu during the meeting.<br />

f) TASK FORCE on <strong>IEEE</strong>-IEC CROSS REFERENCE – J. Sim Progress is held up waiting for work to<br />

be completed on the new editions of IEC 60076-1 (General) and IEC 60076-2 (Temperature rise for oilimmersed<br />

transformers). Phil Hopkinson is leading the IEC effort for IEC 60076-1 and work is expected<br />

to be completed in late 2010. He has previously volunteered to do the comparison work. IEC 60076-2 is<br />

further behind and is being circulated as a 2 nd CD in June. It will be completed after IEC 60076-1. A<br />

new question was raised if there is any IEC information on moisture in paper. There isn’t any. However,<br />

there is a CIGRE document published. The <strong>IEEE</strong> TF has used this information for their work.<br />

g) TASK FORCE on <strong>IEEE</strong>-IEC Harmonization – Jeewan Puri - The issue of <strong>IEEE</strong>-IEC Standards<br />

Harmonization process has been discussed at numerous previous meetings. At the Fall ’08 meeting of<br />

Admin SC a TF was created, under the auspices of Standards SC with Jeewan Puri as Chair. In order to<br />

develop a clear understanding of standards harmonization process, for the TC membership, Mr. Puri then<br />

had discussions with Ms. Jodi Haasz - Program Manager of International Standards and some of her<br />

associates at the <strong>IEEE</strong>. Various questions asked by Mr. Puri were as follows:<br />

1. What are the present <strong>IEEE</strong>/<strong>PES</strong> policies toward developing harmonized standards?<br />

2. What are the <strong>IEEE</strong>-IEC harmonized standards supposed to accomplish for the <strong>IEEE</strong> Standards<br />

users?<br />

3. What are the <strong>IEEE</strong>-IEC harmonized standards supposed to accomplish for the IEC Standards users?<br />

4. Is there a defined process for developing a <strong>IEEE</strong>-IEC harmonized standard?<br />

5. What are the rules for adopting all or part of the IEC standards contents?<br />

6. What is the difference between Dual Logo and <strong>IEEE</strong>-IEC Harmonized standard?<br />

<strong>IEEE</strong>/<strong>PES</strong> <strong>Transformers</strong> <strong>Committee</strong><br />

Spring, 2009 Meeting Minutes - Unapproved<br />

No one could find any written agreement or directive from the <strong>IEEE</strong> or IEC that could answer all of these<br />

questions. The TF did find the <strong>PES</strong>-IEC paper on standards harmonization that describes the following<br />

three goals:<br />

1. Shed the image that <strong>PES</strong> is a developer of only U. S. and North American Standards.<br />

2. Develop <strong>PES</strong> standards that are recognized worldwide.<br />

3. Enhance liaisons with standards <strong>org</strong>anizations world-wide.<br />

These goals were first spelled out in the early 90s in the <strong>IEEE</strong> Power Engineering Society's “Vision for<br />

the Future” documents. They are supposed to be the regular policy in practice of some of <strong>PES</strong> standards<br />

developing groups. However, over the years these goals have perhaps faded away and that is why we<br />

have today only a fuzzy concept of what harmonization is supposed to accomplish. Ms. Haasz and her<br />

<strong>IEEE</strong>/<strong>PES</strong> <strong>Transformers</strong> <strong>Committee</strong><br />

Standards Subcommittee Meeting<br />

April 22, 2009 Hilton Hotel, Miami Florida, USA<br />

associates have informed me that at this time we have the following two options available for adopting a<br />

part of an IEC standard, or an IEC standard in its entirety:<br />

1. <strong>IEEE</strong> Standards group can help us obtain IEC permission for adopting any part of an IEC<br />

Standard, if any one of us so desires.<br />

2. <strong>IEEE</strong> Standards group can help us adopt an IEC standard in its entirety by issuing it as a dual logo<br />

document. Such standards are typically developed jointly by <strong>IEEE</strong> and IEC participants. The details of<br />

this process are provided in the Dual Logo Update Presentation.<br />

I believe that the central goal of our Task Force should be to develop recommendations for the<br />

<strong>Transformers</strong> <strong>Committee</strong> and the <strong>IEEE</strong> <strong>PES</strong> for adopting a clear policy toward the harmonization process<br />

for <strong>IEEE</strong> and IEC standards. Our recommendations should be based on the needs of the users and the<br />

transformer manufacturers. We should clearly evaluate the merits of developing <strong>PES</strong> standards that are<br />

recognized worldwide. We should define as to how and if such standards can indeed benefit the industry.<br />

We should also review and simplify the present process of accessing and adopting IEC information for<br />

developing harmonized documents in the future. The final deliverable of our work should be a position<br />

paper summarizing these issues.<br />

5.5 Old Business<br />

None noted.<br />

5.6 New Business<br />

a. C57.144 - Guide to Metric Conversion of Transformer Standards – Peter Balma – This standard<br />

will expire at the end of 2009. Mr. Peter Balma volunteered to lead the reaffirmation.<br />

b. Insulation Fluids Terminology – Mr. Pat McShane raised a concern about trying to obtain a<br />

standardization of terminology for fluids and liquids, mineral oil, dielectric fluids etc, throughout all our<br />

transformer standards. The first question is -should it be pursued. The second question is -who would do<br />

it. Tom Prevost recommended that documents be changed as documents go through revision. The<br />

concern should go back to Insulating Fluids Subcommittee for a decision and plan.<br />

c. Class I / Class II – Jim Graham recommended an “owner” be established to determine if the Class I /<br />

Class II designation should be removed from the C57 standards. This subject was raised at a prior main<br />

committee meeting (Spring '08) with no follow up action taken. The Standards Subcommittee chair<br />

agreed to sponsor a Task Force that will conduct a poll to determine if the Class I / Class II designation<br />

should be removed from the C57 standards. Gael Kennedy agreed to serve as Chair, with members Steve<br />

Schull, Jim Graham, & Jin Sim.<br />

5.7 Adjournment<br />

The motion to adjourn was made by Chair, and hearing no objections; the meeting adjourned around 5:30PM.<br />

Excerpting from the website: “The Standards Medallion is awarded for major contributions to<br />

the development of standards. Examples of such contributions may include leadership in<br />

standardization of new technologies, assuring achievement of standards development goals,<br />

identifying opportunities to better serve the needs of standards users or other such contributions<br />

viewed as deserving of this award…” Please review, and if you have suggestions for<br />

nominations see our <strong>Committee</strong> Awards Chair.<br />

6.4 <strong>PES</strong> <strong>Transformers</strong> <strong>Committee</strong> Distinguished Service Award<br />

We will continue to present our <strong>PES</strong> Technical <strong>Committee</strong> Distinguished Service Award each<br />

year to one of our members who is recognized by his peers as having contributed significantly<br />

and consistently to <strong>Committee</strong> Standards activities. Excerpting from the <strong>PES</strong> Awards website:<br />

“Each Technical <strong>Committee</strong> is encouraged to make one award for outstanding service. This<br />

personal recognition acknowledges the efforts of those individuals whose sustained performance,<br />

over many years, has contributed to the advancement of the committee technology.” Please see<br />

the Awards Chair if you have suggestions for future recipients.<br />

6.5 <strong>PES</strong> Working Group Recognition Awards<br />

In addition to the Technical <strong>Committee</strong> distinguished service Awards, <strong>PES</strong> sponsors Working<br />

Group Recognition awards. The awards are related to “outstanding and timely” publications of<br />

technical reports, or of standards and guides. Excerpting from the <strong>PES</strong> website<br />

(http://www.ieee.<strong>org</strong>/portal/site/pes/) Awards pages:<br />

“The <strong>PES</strong> Working Group Recognition Awards recognize “the most outstanding and timely<br />

publications” by a <strong>PES</strong> Working Group (or <strong>Committee</strong> or Subcommittee) from among the<br />

nominations. The <strong>PES</strong> Recognition Award is divided into two categories: 1) for technical<br />

reports; 2) standards and guides. Each Technical Council <strong>Committee</strong> may nominate one report<br />

from each category, published by <strong>IEEE</strong>, during the previous three year period.” This award<br />

consists of a plaque which will be presented to the Working Group Chair at the <strong>PES</strong> Summer<br />

Meeting Awards Luncheon. A framed certificate will be presented to each Working Group<br />

member at a designated meeting of the parent Technical <strong>Committee</strong>. Each Technical Council<br />

<strong>Committee</strong> is urged to submit one electronic copy of nominations for each of these awards no<br />

later than November 14.<br />

In November the <strong>Transformers</strong> <strong>Committee</strong> nominated the Distribution Substation Transformer<br />

Working Group for consideration for the 2009 <strong>PES</strong> Working Group Recognition Award. The<br />

nomination cited this WG’s development of a new standard, <strong>IEEE</strong> Std C57.12.36-2007 - <strong>IEEE</strong><br />

Standard Requirements for Liquid-Immersed Distribution Substation <strong>Transformers</strong>. This new<br />

standard filled a void for a unique class of substation transformers that was not suitably covered<br />

by existing standards for either power transformers or pad-mounted distribution transformers.<br />

The WG put substantial effort into development of this new standard, and the result is a<br />

document useful and valuable to both users and manufacturers of this class of transformer<br />

equipment. We wish the WG well in the <strong>PES</strong> determination of the recipient for this <strong>PES</strong> 2009<br />

award, and in recognition of the WG effort we will present the <strong>Transformers</strong> <strong>Committee</strong> 2009<br />

WG Recognition Award to WG Chair David A. Aho, and Vice Chair John R. Rossetti. Those<br />

awards are noted in section 6.1 of this report. Please forward suggestions for nomination for the<br />

6.6 <strong>Transformers</strong> <strong>Committee</strong> Meritorious Service Awards<br />

As indicated in the Awards Report from our Spring 2008 Meeting, we have initiated a process of<br />

additional recognition for Meritorious Service and Outstanding Contributions to the <strong>Committee</strong>.<br />

Suggested qualifications have been developed from a review of similar awards presented by<br />

other <strong>IEEE</strong> Technical <strong>Committee</strong>s or Societies. Initially, qualifications for the award could be<br />

one of the following:<br />

• To recognize continuing exemplary service in notable technical contributions to multiple<br />

<strong>Committee</strong> projects/documents over a sustained period of time<br />

• To recognize an achievement of major value and significance to the <strong>Committee</strong>. The<br />

achievement can be a specific, concisely characterized accomplishment, as opposed to a<br />

collection of different efforts.<br />

• As with the <strong>IEEE</strong> Education Society Meritorious Service Award – “to recognize pioneering<br />

contributions to the administrative efforts of the Society over a period of years, as evidenced<br />

by dedication, effort, and contributions.”<br />

If you have any additional thoughts on qualifications for Meritorious Service Awards, and if you<br />

have potential nominees to suggest, please contact me (individual contact for nominees, to<br />

maintain an element of surprise). Award nominees will be reviewed by the Awards Chair and<br />

the SC Officers. Two Awards for Outstanding Contribution to the <strong>Committee</strong> will be presented<br />

at this Meeting in Miami. This report will be updated after the meeting to include those awards.<br />

Revision 1 – Addendum to Clause 6.6<br />

Outstanding Contribution to the <strong>Committee</strong>: The development and preparation of the<br />

compilation on CD of the C57 Transformer Standards collection – for distribution at the Spring<br />

2008 Meeting – involved significant effort by quite a few <strong>Committee</strong> Members and <strong>IEEE</strong><br />

representatives. This CD provides great value to our members and participants. The <strong>Committee</strong><br />

appreciates the efforts of all who participated in this development, and in particular recognized<br />

Bill Chiu, and our <strong>IEEE</strong> Liaison Matt Ceglia, by presenting them with Outstanding Contribution<br />

Awards in Miami.<br />

6.7 Member Certificates<br />

The <strong>Committee</strong> Officers have approved a plan to provide a framed certificate, certifying<br />

Membership in the <strong>Committee</strong>, to new Members. We hope to start that process at this meeting,<br />

and are finalizing plans to do so. The intent is to provide a symbol of recognition of<br />

Membership status, in a format suitable for display. The certificate will indicate date of<br />

acceptance into the <strong>Committee</strong>, and will be signed by the <strong>Committee</strong> Chair. Depending upon<br />

the response to this recognition program we will also plan, over the next several meetings, to<br />

provide similar framed Membership Certificates to all who are presently <strong>Committee</strong> Members.<br />

The wording will be modified, as these certificates will not be indicating acceptance into<br />

Membership, but rather will be a recognition and acknowledgement of ongoing Membership. As<br />

ecords of acceptance dates may be limited, we may not be including such dates on these<br />

Certificates.<br />

6.8 Nominations for <strong>IEEE</strong>, <strong>PES</strong>, and Technical Council Awards<br />

There are no nominations in these categories at this time. Regarding <strong>IEEE</strong> Fellow Nominations,<br />

we’ve unfortunately missed the boat for preparation of nominations for the 2009 Class of <strong>IEEE</strong><br />

Fellows – let’s do what we can to make sure at least one or more of our members are nominated<br />

and accepted for the 2010 Class of Fellows. Borrowing from the <strong>IEEE</strong> Awards web pages<br />

(http://www.ieee.<strong>org</strong>/web/membership/grade_elevation/grade_elevation.html): “The grade of<br />

Fellow recognizes unusual distinction in the profession and shall be conferred only by invitation<br />

of the Board of Directors upon a person of outstanding and extraordinary qualifications and<br />

experience in <strong>IEEE</strong>-designated fields, and who has made important individual contributions to<br />

one or more of these fields.” Nominations, including references by at least five present <strong>IEEE</strong><br />

Fellows and optional additional endorsements, must be completed and submitted by March 1 of<br />

each year for the following year’s Class of Fellows. If you have a suggestion and are willing to<br />

help assemble the nomination, let me know and I will assist in the process.<br />

Revision 1 – Addendum to Clause 6.8<br />

Ramsis Girgis provided some practical suggestions on how to get the Fellow nomination process<br />

moving:<br />

� Poll <strong>Committee</strong> Members who have been <strong>IEEE</strong> Senior members for at least 10 years to<br />

determine their interest in possible nomination for Fellow grade. If interested, these<br />

Members can submit an outline of their qualifications<br />

� Submit names/qualifications to a small team of <strong>IEEE</strong> Fellows from within our <strong>Committee</strong><br />

membership<br />

� Review/recommendation by the <strong>Committee</strong> Fellow team advising which nominations<br />

should proceed.<br />

We’ll look into determination of <strong>IEEE</strong> Senior Member status and Fellow status within our<br />

<strong>Committee</strong> membership, and will keep you posted as we start this process.<br />

Recognition and awards provide motivation and encouragement to our members to perform at<br />

their highest level, and provide a welcome reward to those who do. Recognition should not be<br />

given lightly, but the accomplishments, talents, and dedication of many of our members and<br />

participants are worthy of recognition – we should look for more opportunities for appropriate<br />

recognition. With your help we’ll do so. Please bring any other suggestions you might have for<br />

additional recognition and/or awards to my attention.<br />

Respectfully submitted,<br />

8.1 Dry Type <strong>Transformers</strong> SC Chair Charles Johnson<br />

8.1.1 Introductions and Approval of Minutes<br />

The Dry Type Transformer <strong>Committee</strong> meeting began at 1:30pm Wednesday, April 22 in the Concerto C/D<br />

room of the Miami Hilton Downtown with introductions of members and guests. There were 10 members and<br />

8 guests present. The Chair introduced the new SC secretary, Lewis Powell. Paulette Powell made a motion to<br />

approve the minutes of the Porto meeting; Roger Wicks seconded and the WG approved. The Chair then asked<br />

if anyone knew of any patent related issues; none were identified.<br />

Working Group/Task Force Reports<br />

The next order of business was the presentation of the reports of the various working groups and task<br />

forces. See the following sections for the individual reports:<br />

8.1.2.1 WG Dry Type Thermal Evaluation C57.12.56/60 Chair Roger Wicks<br />

The WG did not have a meeting. Roger has editorial comments from <strong>IEEE</strong> and said he is struggling to get the<br />

draft in the <strong>IEEE</strong> format. Casey Ballard will supply coil drawings for inclusion in the draft.<br />

8.1.2.2 WG for Revision of <strong>IEEE</strong> C57.16: Dry Type Reactors Chair Richard Dudley<br />

The W.G. for the Revision of <strong>IEEE</strong> C57.16 (Dry Type Reactor T.F.) met on April 20, 2009 at 8:00 a.m. in the<br />

Tenor Meeting Room, of the Hilton Miami Downtown Hotel, in Miami, Florida. There were 13 members and 8<br />

guests present. The following are the highlights:<br />

1. Introductions were made.<br />

2. The minutes of the Porto, Portugal W.G. meeting were approved.<br />

Note: The minutes of the Miami meeting won’t be approved until the meeting of the W.G. in Lombard,<br />

Illinois.<br />

3. There are no patent issues re the revision of <strong>IEEE</strong> C57.16.<br />

4. The remainder of the meeting focused on Draft #3 of the Revision of <strong>IEEE</strong> C57.16, and outstanding input<br />

received on the previous Draft #2.<br />

(i) WG consensus supported the Chairman’s proposal to handle the proposed extension of the turnto-turn<br />

test to BIL’s up to 550 kV in Note 6 of Table 5 and a NOTE in Clause 11.3.5.1. Due to<br />

the fact that fully commercialized test agreement is not readily available, the turn-to-turn test can<br />

be extended to BILs above 200 kV based on availability of test equipment and agreement between<br />

purchaser and manufacturer.<br />

(ii) The Chairman’s proposal to handle the optional impulse design test consisting of 15 shots of<br />

positive polarity in a NOTE in Clause 9.3.3 and a NOTE in Clause 11.3.6 was accepted. Wording<br />

will be added that the test is only applicable to sub-transmission and transmission class reactors.<br />

Due to the statistical nature of the test, 2 flashovers allowed out of 15 shots, it is also<br />

recommended to perform the test on a “mock-up” since a flashover could involve the non<br />

restoring insulation of the reactor under test. The NOTE in Clause 9.3.3 should be “tabbed”.<br />

(iii) All NOTES in the Revision of <strong>IEEE</strong> C57.16 should be “tabbed”<br />

(iii) Pierre Riffon’s draft discussion on the differences between European and North American<br />

distribution systems and the need for CLRs in North American distribution systems will be<br />

included in Annex F which covers potential CB TRV issues associated with the application of<br />

CLRs. Suitable technical papers will be referenced; including one by Jan Car. The impact of the<br />

location of the CLR with respect to the CB will be included; reactor after CB creates a potential<br />

fault current magnitude risk to the CB vs no risk to the CB if the CLR is before the CB. The CB<br />

application guide will also be referenced.<br />

(iv) In the Introduction to Annex F and also in the “Introduction” of the revised standard, the rationale<br />

for including Annex F will emphasize that it is based on the fact that capacitors used to mitigate<br />

the TRV seen by a CB, due to the application of CLRs, are often part of the scope of supply of the<br />

reactor; and may even be mounted inside distribution class CLRs. HV series reactors often have<br />

separately mounted HV capacitors; again also part of the scope of supply of the reactor.<br />

(v) Reactors used in shunt capacitor banks may impact the TRV seen by CBs. Peter Balma will<br />

provide input.<br />

(vi) Devki Sharma will bring up the purpose of Annex F at the next CB SC meeting of the <strong>IEEE</strong><br />

Switchgear <strong>Committee</strong>. He will solicit input from CB SC members such as Ken Edwards.<br />

(vii) The chairman will provide Devki a copy of Draft #3 ASAP. Devki Sharma will become a<br />

member of the WG.<br />

(viii) Information in E.7 “Connections” on short circuit was deemed sufficient by the WG.<br />

(ix) Measurement of the inductance of 3 phase stacked filter reactors will be included in Annex A;<br />

including zero, positive and negative sequence at fundamental and harmonics. Xiangfu Guo &<br />

Klaus Papp will provide input.<br />

6. The revision of the SR switching guide will go out for ballot in the near future and Dry Type TF members<br />

are encouraged to participate.<br />

7. The Chairman stated that he would include the preceding in Draft #4. Since the Revision of <strong>IEEE</strong> C57.16<br />

is essentially complete, the Chairman requested that WG members start to focus on editorial corrections that<br />

could be included in Draft #4. Draft #4 will be distributed well before the Ocotber 26, 2009 meeting in<br />

Lombard,<br />

The WG adjourned at 9:15 a.m.<br />

8.1.2.3 <strong>IEEE</strong> PC57.12.52 - Sealed Dry Type Power <strong>Transformers</strong> Chair Sheldon Kennedy<br />

The Working Group met on Monday, April 20, 2009 at 9:30 AM with 7 members and 4 guests present. Sheldon<br />

Kennedy chaired the meeting.<br />

The <strong>IEEE</strong> disclosure statement was read. There were no patents pertaining to this standards work for which any<br />

members had awareness.<br />

Minutes of the October 6, 2008 meeting in Porto, Portugal were reviewed and approved.<br />

The Chair reminded everyone that this was an old NEMA document that had been brought into <strong>IEEE</strong> and<br />

needed to be changed to the <strong>IEEE</strong> format. Also, the document is old and much of the information is outdated.<br />

The document was reviewed though Clause 8.7 at the last meeting. Chuck Johnson had volunteered to review<br />

the last three pages of the standard and make comments. These were discussed.<br />

Clause 9.1 and 9.2 on High Voltage and Low Voltage Connection arrangements will be deleted since it limits<br />

the transformer construction and these transformers are built in several styles of transformers today.<br />

Clause 9.3 on Surge Arresters will remain.<br />

April 19-23, 2009<br />

Page 41 of 160

April 22, 2009 – Miami, Florida<br />

Clause 9.4 on Unit Substation applications will remain but be checked with C57.12.70 for correctness. The first<br />

paragraph will be kept and the second paragraph on tap changers will be deleted.<br />

Clause 9.5 on Pressure Alarm Switches will be kept but reviewed for correctness.<br />

Clause 9.6 on High Temperature Alarm Switch’s will be kept but reviewed for correctness.<br />

The second sentence of Clause 9.7 concerning Current <strong>Transformers</strong> will be deleted.<br />

Clause 9.7.1 will be modified to say “If specified, but when no other details are given, single-ratio current<br />

transformers with relay accuracy class shall be provided.”<br />

Clause 9.7.2 will be modified to say “If specified, but when no other details are given, current transformers<br />

shall be multi-ratio with relay accuracy class (full winding) and taps as specified by ANSI/<strong>IEEE</strong><br />

C57.13.XXXX.<br />

Clause 9.8 will be reworded to “When specified, enclosed terminal blocks shall be located in the low voltage<br />

segment, unless specified otherwise.”<br />

Clause 9.8.1 and 9.8.2 will remain as is.<br />

Clause 9.9 will be eliminated.<br />

Clause 10 Other Tests – Will be reworded to refer to the latest version of C57.12.01-XXXX.<br />

This completed the review of the document. The Chair will submit a new Draft 2 to the Working Group to<br />

review.<br />

There was no other old business or new business.<br />

The meeting was adjourned at 10:30 AM.<br />

8.1.2.4 <strong>IEEE</strong> PC57.12.91 - Dry Type Test Code Chair Derek Foster<br />

1 The working group met at 3:15 pm with 6 members and 6 guests present.<br />

2 There were no patent issues regarding this standard.<br />

3 The minutes of the last meeting, held in Charlotte, were approved as written.<br />

4 Old Business<br />

The Chairman reminded the Working Group that the PAR for revision of this standard has been approved until<br />

December 2010.<br />

The revision includes four sections of the standard, resistance measurements, dielectric tests, temperature rise<br />

test and audible sound level measurements.<br />

The first three of these sections have been discussed during the last several meetings and revisions have been<br />

agreed on by the Working Group, so the meeting was spent on a final review of these sections prior to going<br />

out to ballot.<br />

There was some discussion regarding the note to clauses 11.6 and 11.7. This note had been changed for this<br />

revision to make it consistent with a similar note in the section of the standard on resistance measurements. But<br />

<strong>IEEE</strong>/<strong>PES</strong> <strong>Transformers</strong> <strong>Committee</strong><br />

Miami, Florida<br />

April 19-23, 2009<br />

Page 42 of 160

April 22, 2009 – Miami, Florida<br />

the second sentence of this note refers to a value to be used for Tk for the correction of stray losses and it was<br />

decided to remove this sentence since clauses 11.6 and 11.7 refer to calculation and correction of temperature<br />

rise values only.<br />

The section of the standard on audible sound level measurements was to be replaced by the revised document<br />

received from the Audible Sound and Vibrations subcommittee, but this document has been delayed pending<br />

further revision. So it was decided to proceed to ballot the standard without this revision.<br />

5. There being no new business, the meeting was adjourned at 4:20 pm.<br />

8.1.2.5 <strong>IEEE</strong> PC57.12.01 - Dry Type General Requirements Chair Tim Holdway<br />

The working group met in the Tenor room of the Hilton Miami Downtown.<br />

The meeting was called to order at 11:05 AM by Chairman Tim Holdway<br />

The meeting was convened with nine (9) members and six (6) guests present.<br />

After the introductions were made, Charles Johnson informed the group that Chairman John Sullivan<br />

had called and informed him that he was resigning his position as Chairman effective immediately.<br />

Chuck then introduced the new Chairman, Tim Holdway.<br />

The minutes of the Charlotte March 17, 2008 meeting were approved.<br />

Motion: Chuck Johnson<br />

Second: Mark Gromlovits<br />

Attendees were asked if they knew of any patents that may be related to the work of this working<br />

group. No patents or patent claims pertinent to C57.12.01 were identified by working group<br />

members.<br />

Old business<br />

Table 5<br />

During the Charlotte meeting, a discussion of removing Note “a” from Table 5 was discussed. It<br />

was decided in Charlotte that note “a” was only applicable to the two tables published in the<br />

previous edition of C57.12.01. Table 5 replaced these two tables in C57.12.01-2005. Note “a”<br />

was inadvertently brought forward into the 2005 issue of the standard during revision. During<br />

this meeting, Phil Hopkinson also added that the low frequency test levels in Table 5 were not<br />

only higher than the levels of C57.12.00 for liquid, but they were also above the typical level the<br />

equipment would see once installed with the exception of fast transients caused by switching.<br />

Chuck Johnson noted that he was aware of few, if any, test failures had occurred since the low<br />

frequency test levels were modified.<br />

The working group agreed by consensus to eliminate note “a” in Table 5 and to leave the low<br />

frequency levels as they now appear. The Chair will pursue obtaining an erratum as a carry over<br />

action from the last meeting in Charlotte on March 17, 2008.<br />

Partial Discharge<br />

Yunxiang Chen opened this discussion in Charlotte. Chuck Johnson and Mike Iman summarized<br />

the previous discussion since Yunxiang Chen was not present.<br />

April 22, 2009 – Miami, Florida<br />

Chuck Johnson reminded the group that reaffirmation of C57.124 <strong>IEEE</strong> Recommended Practice<br />

for the Detection of Partial Discharge and the Measurement of Apparent Charge in<br />

Dry-Type <strong>Transformers</strong> was upcoming and any changes to C57.12.01 should correlate with this<br />

standard<br />

The discussion centered around Section 5.10.3.5 and Table 6. The previously discussed<br />

procedures and measurement levels from Charlotte were questioned after the minutes were<br />

approved. Charles Johnson again proposed harmonization with IEC and Ray Bartnikas added<br />

that the level of 10pC was close, but within, the threshold of measuring equipment. Mark<br />

Gromlovits suggested that a low level, such as 10pC, would require manufacturers to purchase<br />

new, more expensive equipment and that investment could put smaller manufacturers in financial<br />

risk.<br />

Phil Hopkinson suggested that the 10pC level was too low, but would support keeping the<br />

description that allows ‘coils only’ testing with customer approval.<br />

The attendees agreed that further discussion should involve the two people who drove the<br />

discussion in Charlotte – Yunxiang Chen and Rick Marek. Yunxiang will be contacted by Derek<br />

Foster and Rick will be contacted by Charles Johnson to get their input and invite them to the<br />

next meeting in Chicago. The general agreement was Section 5.10.3.5 and Table 6 could be<br />

simplified to describe the voltage levels as a percentage, duration, and definition, in pC. Mark<br />

Gromlovits agreed to propose new wording and test levels to be sent to Tim Holdway for<br />

distribution to the working group members for review before the next meeting.<br />

Proposal for a change to paragraph 4.2.5<br />

Rick Marek presented his proposal to revise clause 4.2.5 at the Charlotte meeting. Rick was not<br />

present at this meeting and his proposal was not discussed. Rick will be asked to attend the next<br />

meeting by Charles Johnson to describe his proposal in detail.<br />

New business<br />

There was no new business<br />

With no further business, the meeting was adjourned at 12:10 PM.<br />

8.1.3 Old Business<br />

There was no old business<br />

8.1.4 New Business<br />

The chair provided the following status of standards:<br />

Meeting Minutes / Significant Issues / Comments:<br />

A welcome was made by the Steve Shull explaining that Ken Hanus was unable to attend and he had<br />

asked him to conduct the meeting.<br />

A roll call of members was made. This showed that 28 were in attendance of the 53 members. This<br />

established a quorum.<br />

At this point, the Steve asked that the guests introduce themselves. Rosters were circulated to provide a<br />

permanent record of attendance for the meeting.<br />

Steve asked if everyone had a chance to review the minute of the last meeting. There wasn’t very much<br />

response to the request. However, Lee Mathews made a motion that the word “motion” be replaced with<br />

“recommended” because a quorum was not established at the fall 2008 meeting. This change was<br />

seconded by Ed Smith. There was not any discussion and the motion passed. The minutes were<br />

accepted as amended.<br />

Steve discussed the requirement for membership in the main committee. He was not sure what Ken had<br />

in mind for this entry but he explained that to obtain main committee membership, the individual must<br />

have the recommendation of two working group chairman and a subcommittee chairman, all who can<br />

verify that the individual has been an active participant for two years (four meetings). He stated the form<br />

is available on the Transformer <strong>Committee</strong> web site. He also pointed out that the applicants<br />

qualifications, e.g. resume, list of accomplishments with the committee working groups must be submitted<br />

with the application. Obviously, it is important to make sure that the submission is clear and neatly<br />

written.<br />

The following reports were submitted by the working groups:<br />

• C57.12.20 – Overhead Distribution <strong>Transformers</strong><br />

♦ Various dimensions were reviewed on a number of the drawings as well as details of the<br />

some of the figures. A gasket survey was reviewed to help determine the temperature<br />

limits of the gasket material used on distribution pole transformers. No conclusions were<br />

reached. Alan Wilks announced that he was retiring and a new co-chair from the<br />

manufacturer sector would be needed<br />

• C57.12.32 Standard for Submersible Equipment – Enclosure Integrity was reaffirmed.<br />

• C57.12.31 – Standard for Pole-Mounted Equipment – Enclosure Integrity – Draft 3<br />

♦ This standard has gone through an editorial review and various issues were corrected. A<br />

few other details were finalized. The members then approved the standard to go to<br />

ballot. The chairs will initiate the ballot.<br />

• C57.12.30 – Standard for Pole-Mounted Equipment – Enclosure Integrity for Coastal<br />

Environments – Draft 3<br />

8.2 Distribution Transformer Subcommittee Report<br />

♦ An editorial review was done on the document with more work to be done before ballot<br />

could be considered.<br />

• C57.12.33 – Loss Evaluation Guide for Distribution <strong>Transformers</strong><br />

♦ The WG sought guidance from the Distribution Transformer Subcommittee and the<br />

administrative Subcommittee as to where this WG should be placed. The WG<br />

recommends that it would be best housed in the Performance Characteristics SC as it<br />

can address the needs of both power and distribution transformers. The WG agrees that<br />

this work should be submitted as a PAR to revise C57.120 and C57.12.33 should be<br />

abandoned. The title should be changed to “Loss Evaluation Guide for <strong>Transformers</strong> and<br />

Reactors”. The present WG Chair and Co-Chair have offered to continue to serve in<br />

these capacities.<br />

• 12.34 – 3-phase Pad-Mount <strong>Transformers</strong><br />

♦ The document has gone through a straw vote. Most of the items that were raised were<br />

address in the meeting. It was also decided to change the 480 volt limit to 600 volts.<br />

With these additions and corrections, it was voted to move the draft to ballot.<br />

• C57.12.37 – Electronic data transformer<br />

♦ The working group discussed the addition of the DOE values to this document so as to<br />

be in harmony with the changes made in C57.12.00. Also Rich Hollingsworth announced<br />

his retirement and a new co-chair from the manufacturer sector would soon be needed.<br />

• C57.12.38 – 1 phase Padmount transformers<br />

♦ Draft 6.4 was approved with one negative and it will be sent to RevCom with one<br />

negative, which was addressed.<br />

• C57.15 – Step Voltage Regulators<br />

♦ This standard was balloted and was in the process of addressing the comments. There<br />

was some discussion but nothing was resolve. It was decided to send the comments to<br />

the working group for further review before the next meeting.<br />

• TF Transformer Efficiency and Loss Evaluation (DOE)<br />

♦ There were a number of items brought forth during the meeting to which there was a<br />

great amount of discussion. However nothing was finalized. The plan was to work on<br />

determining a better understanding of few items by the next meeting.<br />

There was no Old Business.<br />

Under new business, Rich Hollingsworth made a motion to dispense with the TF on Transformer<br />

Efficiency and Loss Evaluation (DOE) after the next meeting. Bob Olen seconded this motion. There<br />

was a fair amount of discussion. Phil Hopkinson asked that the TF be extended until after the spring<br />

2010 meeting. Ed Smith comment that the TF should determine when their work is completed and then<br />

make the recommendation to the subcommittee to be disbanded. Gael Kennedy asked for a point of<br />

order to clarify who can establish and also disband the TF. Matt Ceglia stated the subcommittee per the<br />

established procedures has the right to appoint and disband WG/TF but he cautioned the group that<br />

motions should not be made about future actions, because conditions can change and thus these actions<br />

may not be in the best interests of the subcommittee. A motion was made to change “after next meeting”<br />

to “after two meetings”. The amendment was made and seconded and passed with 16 yes votes, 3 no<br />

votes and 9 abstentions. The amended motion was voted and failed with only one in favor.<br />

Jerry Corkran asked to address the committee concerning some issues with the C57.152 field test guide.<br />

He indicated that it has been proposed to add a PF requirement level to this guide. He stated C57.12.90<br />

8.2 Distribution Transformer Subcommittee Report<br />

NOTE 3—A factory power-factor test will be of value for comparison with field power-factor<br />

measurements to assess the probable condition of the insulation. It has not been feasible<br />

to establish standard power-factor values for liquid-immersed transformers for the following<br />

reasons:<br />

a) Experience has indicated that little or no relation exists between power factor and<br />

the ability of the transformer to withstand the prescribed dielectric tests.<br />

b) Experience has shown that the variation in power factor with temperature is<br />

substantial and erratic so that no single correction curve will fit all cases.<br />

c) The various liquids and insulating materials used in transformers result in large<br />

variations in insulation power-factor values.<br />

This has been in this standard for many years. He went through some examples of PF measurement in<br />

various conditions and encouraged the membership to get involved in this working group to prevent them<br />

from writing something that is direct conflict with C57.12.90 and possibly providing misleading PF values<br />

for diagnostic purposes.<br />

The meeting adjourned at 10:45 AM.<br />

8.3 Dielectric Test Subcommittee – Loren Wagenaar, Chair; Thang Hochanh,<br />

Vice-Chair; Dennis Marlow, Secretary<br />

The Dielectric Test Subcommittee (DISC) met on Wednesday, April 22, 2009 at 11:00 am in Miami with<br />

63 of 119 members, and 67 guests present. 14 of the guests requested membership and are welcomed<br />

into the Subcommittee.<br />

8.3.1 Chair’s Remarks<br />

8.3.1.1 Loren Wagenaar was unable to attend for personal reasons. Vice Chair Thang<br />

Hochanh Chaired the meeting.<br />

8.3.1.2 The Vice Chair briefly reviewed highlights of the Administrative Subcommittee<br />

meeting held on Sunday:<br />

The next meetings:<br />

Fall 2009, October 25-29 (Westin $149) – Lombard IL USA Exelon<br />

Spring 2010 , March 7-11 ( firm date) – location to be determined<br />

8.3.1.3 After introductions a count showed 59 members were in attendance.<br />

Subsequent arrival of 4 members met the new quorum requirements<br />

8.3.1.4 The minutes of the fall 2008 meeting in Porto were approved as written, and are<br />

available on the <strong>IEEE</strong> <strong>Transformers</strong> <strong>Committee</strong> Web Site.<br />

8.3.2 Working Group Reports<br />

8.3.2.1 Working Group on Revision of Low Frequency Tests – Bertrand Poulin, Chair;<br />

Bill Griesacker, Secretary<br />

At 1:45 PM on April 21, 2009 the meeting was called to order by Chairman B. Poulin. The meeting was<br />

attended by 11 members and 18 guests. After introductions were made, the <strong>IEEE</strong> patent disclosure set<br />

of slides was presented. No patent issues were raised. The agenda was presented and the minutes of<br />

the Porto meeting were accepted as issued. The next order of business was the Task Force reports:<br />

a) TF Electrical Partial Discharge Measurements Guide C57.113<br />

Chairman Dr. Lemke presented minutes of the Task Force meeting held on April 20 th at 8:00 AM where<br />

he presented the status of the document, discussion of comments, and resolution of the next steps. Of<br />

the 119 eligible voters, 108 ballots were returned. This is an 86% return which exceeds the 75%<br />

minimum. There were 98 approvals, no negative votes, and five abstentions. There are 78 comments,<br />

4 of which had to be rejected because there involved modification of the scope, which must match the<br />

PAR. There was a comment about retaining IEC 60270 in the normative reference and moving the<br />

other IEC references to the bibliography. This was acceptable to the task force. Other comments<br />

would be incorporated within the next month in order that the document would be ready for a<br />

recirculation ballot within the next three months. The objective of the Working Group would be that the<br />

Task Force would have the revisions uploaded in the comment resolution spreadsheet, incorporate the<br />

revisions into the document, and initiate the recirculation ballot in hopes that the document would be<br />

completed by end of the year.<br />

b) Task Force Partial Discharge in Bushings and PTs/CTs<br />

Chairman T. Hochanh presented minutes of the Task Force meeting held on April 20 th at 3:15 PM. This<br />

is a new task force and during this meeting two presentations were held on measurement of PD in new<br />

bushings. The intention of this Task force is to develop a guide on PD testing in a test lab setting and<br />

not to include field testing. The need was expressed that Utilities were seeking an <strong>IEEE</strong> guide for PD<br />

testing on these products. The present IEC 602770 and C57.113 would be the foundation documents<br />

for this guide. During this discussion, there were comments by Working Group members that the<br />

balanced bridge method should not be the only method presented in this guide. It was suggested that<br />

the Single-Ended method is also used in making measurements.<br />

The Working Group Chairman gave authorization for the Task Force to research other applicable<br />

methods to be incorporated into the guide. Since this will be a guide and not a recommended practice,<br />

this would be an acceptable approach.<br />

Other discussion on application of the method presently in C57.113 was held where it was commented<br />

that this method would be acceptable if the ambient levels could be achieved. Other ideas, such as<br />

alternative frequencies, were suggested since the circuit of bushings and instrument transformers were<br />

not as complex as transformers.<br />

The Chairman noted that since a large number of ballot comments were made regarding the language<br />

structure in C57.113, the guide for the PD measurement in bushing and instrument transformer would<br />

benefit from this review at the initial writing of the guide. Volunteers were forthcoming to assist the Task<br />

Force Chairman with this task.<br />

c) Old Business:<br />

There were three remaining issues from the previous meetings.<br />

Loren Wagenaar was not able to respond to the issue of pumps running during the Induced test and<br />

whether any measurements should be made before and during the enhanced portion of the test. Since<br />

Loren had other priorities, the Chairman would contact him to check where any information would be<br />

forthcoming.<br />

The last open issue regarding the Induced test was a review of the one hour test for 69 kV and below by<br />

Subhash Tuli. This information will be provided before the next meeting.<br />

With no new business, the meeting was adjourned.<br />

Respectfully submitted by Bertrand Poulin<br />

8.3.2.2 Working Group on Revision of Impulse Tests – Pierre Riffon, Chair; Peter<br />

Heinzig, Vice-Chair<br />

The WG met on April 21, 2009, from 3:15 pm to 4:30 pm. Twenty-seven (27) members and thirty-three<br />

(33) guests attended the meeting. Eleven (11) guests requested membership. The meeting was<br />

chaired by Pierre Riffon, chair of the WG.<br />

The agenda was reviewed and accepted as written.<br />

The minutes of the Porto meeting were approved as written.<br />

The <strong>IEEE</strong> patent disclosure requirement policy was discussed. None of the members and guests<br />

present during the meeting was aware of any patents related to the work of this WG.<br />

Dielectric Test Subcommittee – Unapproved Meeting Minutes<br />

April 22, 2009 – Miami, Florida<br />

The first technical item of business was related to the survey results on a new proposal related to the<br />

grounding of neutral terminal(s) during switching impulse tests. Negatives comments were discussed<br />

and the WG chairman counterproposal was unanimously accepted as is. The revised proposal will be<br />

forwarded to the WG responsible of C57.12.90 for inclusion in the next <strong>IEEE</strong> C57.12.90 draft for ballot.<br />

The second item of business was to discuss the comments received on the survey made on a new<br />

proposal concerning the tap changer position during lightning impulse tests. After discussion, the<br />

proposal will be modified in order to request a lightning impulse test on a tap position giving a bridging<br />

position close to the middle tap position for reactor-type tap changers. Additional wording will be added<br />

stating that the generator components should be set for the first phase to test. Impulse generator<br />

settings shall be kept as is for the remaining two phases even if the resultant wave-shape is out of the<br />

prescribed tolerances. The revised proposal will be surveyed within the WG and Dielectric Tests<br />

Subcommittee prior to the next meeting.<br />

Finally, the last item of business was related to comments received on the survey made on the number<br />

of impulses to be applied during lightning impulse test and switching impulse tests. Due to lack of time,<br />

the comments received were not fully discussed and the discussion on the comments received will be<br />

postponed to the upcoming meeting in Chicago.<br />

The meeting adjourned at 4:30 pm on April 21, 2009. Submitted by Pierre Riffon, P.Eng.<br />

8.3.2.3 Working Group for Revision of the Impulse Test Guides C57.98 and C57.138 –<br />

Art Molden, Chair; Joe Melanson, Co-Chair<br />

No working group meeting was held at Miami<br />

Editorial work on our guide is continuing slowly. Much still has to be done, including transferring the<br />

guide into the new template, translation of JPEG files into TIFFs and including a revised bibliography. It<br />

is hoped that a completed guide will be available before the next meeting.<br />

Respectfully submitted by Arthur Molden, Working Group Chair<br />

8.3.2.4 Working Group on Liquid-Filled <strong>Transformers</strong> Dielectric Test Tables – Phil<br />

Hopkinson, Chair; Scott Choinski, Secretary<br />

Phil thanked all the members for finally completing this work. He indicated that the final values were not<br />

included in the latest ballot of C57.12.00 and that the correct values will be included in the recirculation<br />

ballot.<br />

8.3.2.5 Task Force on External Dielectric Clearances – Eric Davis, Chair; Dennis<br />

Marlow, Secretary<br />

The TF met on April 20, 2009 at 11:00 am at the Hilton Downtown Miami. Thirty-eight people attended<br />

this third meeting, 5 members and 33 guests were present with 3 guests requesting membership,<br />

bringing the total membership to 12.<br />

The minutes from the fall 2008 meeting in Porto were approved as submitted.<br />

Dielectric Test Subcommittee – Unapproved Meeting Minutes<br />

April 22, 2009 – Miami, Florida<br />

The <strong>IEEE</strong> patent disclosure requirement policy was discussed. Reference to the package posted on the<br />

<strong>IEEE</strong> <strong>Transformers</strong> <strong>Committee</strong> Web site was made. None of the members and guests present during<br />

the meeting was aware of any patents related to the work of this TF.<br />

The Chair outlined the purpose as:<br />

� To review and revise as necessary the external dielectric clearances in C57.12.00<br />

Section 6.8 and Table 14<br />

� Document the technical rational for the clearances<br />

The TF again reviewed the progress in determining the technical basis of the clearances contained in<br />

CAN/CSA C88, <strong>IEEE</strong> C57.12.00, the NESC, NEMA TR-1 and IEC 60076-3.<br />

Roger Hayes again reported that the CAN/CSA C88 clearances appear to be based on CAN/CSA<br />

C308, “The Principles and Practices of Insulation Coordination.” This standard refers to an <strong>IEEE</strong> paper<br />

presented in Montreal in early 1970 which has been obtained with the help of Pierre Riffon. Formulas<br />

from this standard will be posted on the <strong>Committee</strong> website.<br />

The Chair made a presentation which summarized the clearances used for system voltages 230 kV based on Switching Surge levels. This presentation<br />

will be posted on the <strong>Committee</strong> website.<br />

In general, for system voltages 230 kV, <strong>IEEE</strong> does not provide values for phase to ground clearances. The<br />

phase to ground values contained in the Canadian standard are lower than those contained in the IEC<br />

standard. The phase to phase values contained in the IEC and Canadian standards are comparable.<br />

The C57.12.00 phase to phase values are much lower.<br />

There were various comments from members and guests about minimum clearances needed for<br />

different altitudes, animals, special cable geometry, bushing grading and other special conditions as<br />

well as the effect of lightning arresters. These have already been noted in section 6.8 of C57.12.00<br />

The NEMA TR-1 clearances for system voltages 230 kV.<br />

The TF felt the phase to phase clearances in C57.12.00 appeared to be very low and the basis for them<br />

should be carefully examined. The TF is also in favor of adding phase to ground clearances. Further<br />

investigation is required.<br />

Once the investigation is concluded, we need to follow the guidelines from IEC, CSA or TR-<br />

1 for both phase to ground and phase to phase clearances. Recommendations must come from just<br />

one standard and should not be a mix of two<br />

The next step is determining the basis of the CAN/CSA and IEC clearances, investigating<br />

the insulation coordination standards <strong>IEEE</strong> 1313.2 and IEC 60071-2 and -2, and investigating the<br />

substation clearances in <strong>IEEE</strong> 1427. The findings will be reported to the TF prior to the next meeting.<br />

Meeting adjourned 12:05 pm Respectfully submitted, Dennis Marlow<br />

8.3.2.6 Task Force on Special Dielectric Test Issues – Bruce Forsyth, Chair<br />

The Task Force on Special Dielectric Test Issues met in Miami, FL on April 20, 2009 at 1:45 PM. There<br />

were 39 people in attendance, 9 members and 30 guests, with 8 guests requesting membership,<br />

bringing the total membership to 42.<br />

After introductions of attendees the minutes of the Fall 2008 meeting in Porto, Portugal were approved<br />

as written. The purpose of the TF, which is to make recommendations to the Chairman of the Dielectric<br />

Test Subcommittee regarding how to proceed with certain dielectric test issues, was reviewed before<br />

moving on to regular business.<br />

The first item of business was a review of a survey question regarding impulse testing of neutral<br />

terminals. The specific question was “Should neutral terminals on all power transformers be impulse<br />

tested routinely?” It was noted that the current standards require impulse testing of neutral terminals<br />

rated 200 kV BIL and higher. There was some discussion related to the relative value of impulse testing<br />

neutral terminals and that in most cases, especially when the neutral is solidly grounded, the neutrals<br />

will not see the same type of impulse stresses as line terminals. In addition, it was noted that the<br />

presence of devices such as load tap changers complicate the issue since impulse tests are primarily<br />

intended to test windings, and depending upon the tap position required for the test, severe upswings in<br />

voltage can occur during test that may never occur in service. Some attendees expressed support for<br />

routine impulse testing based upon factory test floor problems during neutral terminal impulse testing<br />

that they had witnessed. One attendee recalled a test failure due to poor neutral lead routing. There<br />

was some subsequent discussion related to whether that type of problem would be detected by the<br />

routine applied potential test if the neutral terminal had not been impulse tested. During all of these<br />

discussion there appeared to be many attendees who felt there may be some merit to routinely impulse<br />

testing neutral terminals, but that there are many questions and conditions that would need to be<br />

adequately addressed before they were willing to support a proposal at this time. Some attendees were<br />

very clear that they did not believe it was necessary to routinely impulse neutral terminal at all. Other<br />

attendees were very clear that they believed the neutral impulse test is necessary and that is why they<br />

call for it in every specification.<br />

The Chair brought the discussion to a close and asked the TF members to vote on whether there was<br />

sufficient support to pursue this issue further at this time. By a vote of 10-7 the answer was “NO”.<br />

Therefore, by inclusion of this note in these minutes, the TF Chair shall recommend to the<br />

Subcommittee Chairman that no further action be taken on this issue.<br />

The next item of business was a general discussion of the definition of distribution, power, Class I and<br />

Class II transformers. The purpose of the discussion was to begin a dialog related to whether the TF<br />

could (or should) arrive at any recommendation(s) that may benefit the industry since there have been<br />

reports of some confusion regarding the application of these definitions. The confusion appears to be<br />

related to that fact hat the terms “distribution” and “power” are defined by application whereas the terms<br />

“Class I” and “Class II”, which relate only to power transformers, are defined by voltage. It was<br />

mentioned that <strong>IEEE</strong> Std C57.12.36 addresses the requirements for distribution transformers with HV<br />

terminal ratings of up to 69 kV, but some 69 kV transformers are considered to be Class I power<br />

transformers according to the current definitions. As time was running out the discussion was tabled for<br />

review at a later time.<br />

There was no new business raised and the meeting adjourned at 3:00 PM<br />

Respectfully submitted, Bruce Forsyth<br />

8.3.3 SUBCOMMITTEE DISCUSSION<br />

The DI subcommittee questioned the recommendation of the TF with respect to the question about<br />

routine impulse testing of neutral terminals, especially since there were few members of the task force<br />

present at the TF meeting.<br />

After a heated discussion it was passed by a vote of 37 to 22 that it is the will of the DI subcommittee<br />

that the TF continue with their investigation concerning routine impulse testing of neutral terminals.<br />

8.3.4 Liaison Reports<br />

8.3.4.1 High Voltage Test Techniques (HVTT), <strong>IEEE</strong> Standard 4 - Arthur Molden<br />

This par will expire at end of 2009. The standard is from 1995 and must be balloted or it will be<br />

withdrawn. Editorial work on the new revision of High Voltage Testing Techniques, <strong>IEEE</strong> Standard 4<br />

continues. The working group has received the first full draft of the newly revised Standard 4. It is hoped<br />

that we can finish the editorial work and arrange a meeting to review the document ready for<br />

submission to the <strong>IEEE</strong> later this year.<br />

8.3.5 Old Business<br />

8.3.5.1 Tutorial on Dielectric Frequency Response Testing<br />

Tutorial will be scheduled for the fall 2009 meeting, and be sponsored by the Dielectric Test SC. This<br />

will be given at the fall meeting and the 6 presenters will discuss the merits of including diagnostic<br />

technique as a standard or optional test.<br />

8.3.5.2 Class I and Class II <strong>Transformers</strong><br />

The WG/TF chairs are again reminded to report on the additional effects of eliminating differences<br />

between Class I and II transformers.<br />

Jin Sim requested the results of this from the SC. Pierre Riffon and Bertrand Poulin made a hastily<br />

verbal report and during the subsequent discussions, it appears a more detailed analysis is necessary<br />

from the DI SC as well as other SCs.<br />

This will be a formal action item to be reported on at the fall 2009 meeting.<br />

This is repeated again in these meetings for ease of reference:<br />

During discussion of a proposal from the floor at the Charlotte meeting of the main committee to<br />

eliminate Class I and Class II, the Chair of the main committee requested that SC chairs look at the<br />

effect of eliminating these classes. The Chair has consulted the latest proposal of C57.12.00, Class II<br />

transformers require the following routine tests whereas Class I transformers do not:<br />

There was a motion from Phil Hopkinson to eliminate the reference to Class I and Class II from the<br />

dielectric test tables in C57.12.00. There would only be two classes of transformers: Distribution and<br />

Power <strong>Transformers</strong> with all transformers presently designated as Class I or Class II to be named<br />

Power <strong>Transformers</strong>.<br />

This was not approved by a vote of 14 YEA and 28 NO<br />

8.4 HVDC Converter <strong>Transformers</strong> and Smoothing Reactors<br />

Subcommittee – R. Dudley, Chair<br />

The HVDC Converter <strong>Transformers</strong> and Smoothing Reactors S.C. met on April 20, 2009 at<br />

1:45 p.m. in the Picasso Meeting Room of the Hilton Miami Downtown Hotel, in Miami,<br />

Florida. There were 11 members and 15 guests present. The following are the highlights:<br />

8.4.1 Introductions were made.<br />

8.4.2 <strong>IEEE</strong> patent policy was reviewed, and there are no issues re the revision of<br />

<strong>IEEE</strong> 1277.<br />

8.4.3 The minutes of the Porto meeting were approved.<br />

Note: The minutes of the Miami meeting will not be approved until the meeting of the<br />

S.C. in Lombard, Illinois.<br />

8.4.4 The Chairman briefed S.C. meeting attendees on the highlights of the<br />

Administrative SC meeting.<br />

8.4.5 The remainder of the meeting focused on discussion of Draft #3 of the<br />

revision of <strong>IEEE</strong> 1277. Consensus of the SC/WG is that the revision of<br />

<strong>IEEE</strong> 1277 is essentially complete. Final details are to be resolved per WG<br />

agreement detailed below:<br />

(i) Specific details re CIGRE publications on oil conductivity are not yet available;<br />

Ugo Piovan will provide.<br />

(ii) If the capacitor discharge test is performed using an impulse generator, the front<br />

time may be short vs. if a capacitor bank is used, plus a resistor, and a front<br />

time consistent with a switching impulse can be achieved; Clauses 12.5.2.4.2.2<br />

and Clause 129 will be modified.<br />

(iii) Comments received from Lars-Erik Juhlin, plus responses from Pierre Riffon,<br />

were discussed:<br />

Miami, Florida<br />

April 19-23, 2009<br />

- Clause 5.0.5 “Other Unusual Service Conditions”; i, j and l will be deleted as<br />

they are not applicable to SMRs;<br />

- Clause 6.4.2 “Tolerances”; text from Clause 9.0.1.2 will be added re impact<br />

of full rated and SC current;<br />

- Text and figures in Clause 6.7.3 and Annex A will be co-ordinated. Fig. 1c in<br />

Clause 6.7.3 will be changed; eliminate neutral and show a single ground<br />

point as in Fig 1 b.<br />

Page 56 of 160

- Clause 7.2 “Insulating Liquids”; reports of CIGRE working groups referred to<br />

in the second NOTE were not published at the time of final draft of this<br />

revision. The third NOTE will be expanded. Oil conductivity testing is per<br />

IEC 61620 and IEC 60247. The conductivity test is an ac test and test<br />

values may not be directly applicable for HVDC applications, but could be a<br />

useful relative reference.<br />

- A footnote will be added to Table 1 “The DC Applied Voltage Test and<br />

Polarity Revised Test is not applicable for SMRs if the rated DC voltage is<br />

below 15% of the SIWL specified for terminal-to-ground.”<br />

- Lars-Erik Juhlin’s suggestion that information on the impact of overloading<br />

on insulation aging be added to Clause D.2 of Annex D was accepted. The<br />

Chairman will draft text based on LEJ’s input.<br />

- The reference temperature in Clauses 12.4.9 and 12.4.4.5 is 40˚C.<br />

- Re Clause 12.5.3.2, two test methods are allowed; test each terminal with a<br />

LI with other grounded or tie both terminals together and apply the LI to both<br />

terminals simultaneously. However since there may be some risk with the<br />

two terminals tied due to the possibility that the voltage to ground may be<br />

higher than the terminal to ground voltage (traveling waves meet in the<br />

middle of the winding), the preferred test method is to test each terminal with<br />

the other grounded.<br />

(iv) Comments received from Ulf Radbrandt were discussed:<br />

- Clause 3.4 “terminal to ground” should be used vs. “pole to ground”.<br />

- Clause 6.3.2 “Rated dc overload current”; the NOTE will be augmented to<br />

include a reference to Annex D “In Service Overloading of HVDC Smoothing<br />

Reactors”. Note that D.1 should be “Introduction”.<br />

- Clause 8.2.5 “Test Sequence” should be divided into sub clauses that clearly<br />

differentiate between oil-immersed and dry-type; 8.2.5 “Introduction”, 8.2.5.2<br />

etc.<br />

- Clause 2.6.7.1 “the RIV test should be carried out with ac voltage with a<br />

crest value equal to nominal dc voltage +10%. RIV listing with dc has not been<br />

done to-date.”<br />

(v) SC members agreed with the Chairman that Draft #3 was essentially a final<br />

revision in terms of major objectives. The Chairman stated that based on this<br />

and on the above discussions/consensus agreements, he would prepare Draft<br />

#4 as soon as possible. The Chairman also requested that SC members review<br />

Draft #3 in detail re editorial corrections or any other possible errors or<br />

omissions and provide him this input as soon as possible for inclusion in Draft<br />

#4. To facilitate the process, it is suggested that the detailed review be broken<br />

down into three components; Contents: 1 to 11, Contents: 12 and Contents:<br />

Annexes A to G. Draft #4 will be sent to SC members for approval and once<br />

obtained; the Chairman will initiate a formal <strong>IEEE</strong> ballot process.<br />

8.4.6 The Chairman thanked the SC members for their contributions to the<br />

revision process. The meeting adjourned at 3:00 p.m.<br />

8.5 C57.13 Instrument <strong>Transformers</strong> – J. Smith – Unapproved Minutes<br />

8.5.1 Chair’s Remarks & Announcements<br />

The Instrument Transformer Subcommittee met on Wed April 22 at 9:30 AM<br />

7 members and 9 guests attended. The meeting was chaired by J. Smith<br />

The previous meeting’s minutes were approved as written and there were no Patent issues.<br />

The next meeting is scheduled for October 2009 in Lombard (Chicago), Illinois<br />

8.5.2 Working Group Reports<br />

8.5.2.1 Working Group on Test Requirements for High Voltage Instruments<br />

<strong>Transformers</strong> Rated 115 kV and above<br />

The WG met on April 21, 2009. Five (5) members and fifteen (15) guests attended the meeting.<br />

Two guests requested membership. The meeting was co-chaired by Mr. P. Riffon and Mr. Ross<br />

McTaggart.<br />

The agenda has been reviewed and accepted as written.<br />

Minutes of Porto meeting were approved as written.<br />

The <strong>IEEE</strong> patent disclosure requirement policy was discussed. None of the members and<br />

guests present during the meeting were aware of any patents related to the work of the WG.<br />

Draft 5 of revision of C57.13.5 has been successfully balloted within <strong>IEEE</strong> in March 2009. The<br />

approval rate was 93% and 81% of the eligible peoples in the ballot group returned their ballot.<br />

Four negative ballots have been received and three of them have been resolved before the<br />

meeting. One negative ballot still remains to be resolved. The comment associated with this<br />

negative ballot has been reviewed and the WG agreed to not accept the balloter comment. The<br />

single reference to IEC 600270 will remain since it is not possible to use parts of it or to<br />

summarize it in few paragraphs. The WG agreed that this IEC standard should be used as a<br />

whole. Use of ASTM D1868 standard dealing with partial discharge measurements has been<br />

discussed. This document will be reviewed by the Chairman and if it is not conflicting with IEC<br />

600270, we will be put it as an additional document in the Bibliography of D6.<br />

D6 is almost ready to be re-circulated within <strong>IEEE</strong> in the next weeks. Changes made from D5<br />

are clearly indicated, most of them are purely editorial. The document should be ready for<br />

submission to RevCom prior to the PAR deadline (December 2009).<br />

The remaining part of the meeting was dedicated to a presentation from Mrs. Viorika Aresteanu<br />

from Hydro-Québec regarding Instrument <strong>Transformers</strong> Replacement in Hydro-Quebec<br />

Network.<br />

Under Old Business, discussion on the proposal from Mr. Rolando Gomez concerning<br />

dissolved-gas content and acceptable limits is postponed to the next WG meeting.<br />

8.5.2.2 TF on Bushing and Instrument Transformer Partial Discharge<br />

The new task force on Partial Discharge in Bushings and PTs/CTs met on Monday April 20 th ,<br />

2009, at 3:45pm with 46 people attending this first meeting.<br />

After introductions, the agenda for the meeting was presented.<br />

As part of the agenda, there were presentations by Arturo Del Rio (Trench), Guy Laliberte<br />

(Areva) and Viorika Aresteanu (HQ) on factory PD testing of new bushings, factory PD testing of<br />

new instrument transformers and also on test lab PD testing of aged instrument transformers.<br />

The main issues discussed during the meeting were focused on:<br />

• The need for a guide on PD testing of bushings and instrument transformers.<br />

• The scope of this guide to focus on PD testing in test lab settings; not to include field<br />

testing or alternate methods such as acoustic.<br />

• The use of the balanced bridge method for PD testing of bushings and instrument<br />

transformers.<br />

• Need for utilities to have a <strong>IEEE</strong> guideline for PD testing.<br />

• Presently, the main references for PD testing of bushings and instrument transformers<br />

are IEC 60270, <strong>IEEE</strong> C57.113 and ASTM D1868.<br />

Meeting was adjourned at 4:30 pm. Follow up meeting for the Task Force to include additional<br />

presentations on PD issues for bushings and instrument transformers.<br />

A request to continue with the TF is presented.<br />

8.5.3 Review of comments on C57.13 revision<br />

a) Review of presentation on Partial Discharge<br />

Brian Leslie was not in attendance to make the presentation but it was discussed briefly<br />

amongst the attendees. It was generally agreed that the proposed test voltages were too<br />

low and that comments should be submitted to J Smith who will forward to B Leslie.<br />

b) Presentation on sections 8.1, 8.2 and 8.9 by Vladimir Khalin<br />

Mr Khalin proposed the following changes:<br />

1) 8.1.1 Uncertainty Limits.<br />

The uncertainty ratio of the accuracy measuring systems shall be no less then 4:1.<br />

For example:<br />

To test 0.3 class transformer, the system’s ratio error ± .075% and<br />

phase angle ± 2.6 min.<br />

To test 0.15 class transformer, the system’s ratio error ± .037% and<br />

phase angle ± 1.3 min.<br />

2) 8.1.7 through 8.1.10<br />

need to be revised<br />

3) 8.2 Demagnetization<br />

Delete Method 3<br />

4) 8.9 Replace this clause with an inter-turn over-voltage test<br />

c) Review of comments submitted by Randy Mullikin<br />

Most of the comments concern bushing current transformers. It was proposed to add<br />

clauses taking into account the environment in which these CT’s operate, particularly in<br />

transformer applications. There was also a proposal to add a table for high accuracy<br />

CT’s which was different to C57.13.6. The preference is to make it the same as C57.13.<br />

The subject of extended range was also brought up and warrants further discussion. The<br />

comments on the use of spark gaps were discussed it was agreed that the way the<br />

standard is presently worded it appears that they are required whenever the open-circuit<br />

voltage is over 3.5 kV, which was not the intent. The proposed revised wording is<br />

generally acceptable and it was suggested that guidelines should be included for sparkgap<br />

ratings. It was also noted that spark gaps may provide a false sense of security (ie<br />

what happens after 1 minute?)<br />

d) Review of test differences between C57.13 and C57.13.5 by Ross McTaggart<br />

This comparison was done in response to concerns expressed in the previous meeting<br />

regarding the proposal that the next revision of C57.13 should specify that C57.13.5<br />

applies to all Instrument <strong>Transformers</strong> 115 kV and above whether it is specifically called<br />

for or not. The additional test requirements imposed “across the board” may impose<br />

hardships on some manufacturers due to limited test capacity and result in increased<br />

prices to users. The comparison was reviewed and will be distributed to members for<br />

comments.<br />

EPRI thermal data as Excel spreadsheet<br />

CHAIR: The natural ester shows high ethane content compared to mineral oil. Why?<br />

COMMENT (Fredi Jacob): We don’t know if it’s from the base oil or additives.<br />

CHAIR: The oxygen goes down as temperature goes up.<br />

COMMENT (Fredi Jacob): The carbon oxides increase. The oxygen comes from either the ester molecule<br />

or from air as dissolved oxygen.<br />

CHAIR: Two anomalies apparent. The carbon dioxide in mineral oil at 300C is an order of magnitude<br />

higher than the other two temperatures. Acetylene is seen in natural ester at 500C but not in mineral oil.<br />

QUESTION: Could we compare EPRI data to those from the University of Manchester and DuPont<br />

CIGRE work?<br />

COMMENT (Claude Beauchemin): At first glance it seems that there is enough difference between natural<br />

ester and mineral oil to warrant a separate guide.<br />

EPRI thermal data as Duval triangle<br />

QUESTION (Fredi Jacob): The data does not seem to fall into the appropriate boundary areas.<br />

COMMENT (Michel Duval): There is a good deal of uncertainty in the temperature. The T1/T2 and T2/T3<br />

boundaries are moved for natural ester.<br />

CHAIR notes that Michel Duval redefined his triangle for natural esters.<br />

EPRI arcing data as Excel spreadsheet<br />

CHAIR: Acetylene and hydrogen are higher for mineral oil.<br />

QUESTION (Joe Cultrera): What was the level of arcing?<br />

CHAIR: (shows arcing test slide) 50 arcs/min at 140 A<br />

QUESTION (Joe Cultrera): What was the arc energy?<br />

CHAIR: not available here<br />

EPRI arcing data as Duval triangle<br />

CHAIR: The triangle shows D1 for mineral oil and D1/D2 for natural ester.<br />

COMMENT (Michel Duval): Need to shift the D1/D2 boundary for natural ester.<br />

CHAIR requests and receives permission to post Michel Duval’s article on the website.<br />

Motion<br />

Don Cherry moves to propose a separate natural ester gas guide to the Insulating Fluids subcommittee.<br />

Seconds by Michel Duval and Claude Beauchemin.<br />

Discussion:<br />

COMMENT (Michel Duval): We should be careful not to duplicate too much from the mineral oil guide.<br />

CHAIR: suggests using the silicone gas guide as a model (shows draft scope).<br />

CHAIR: How will a retrofill affect the gas interpretation, as 6-7% residual mineral oil has been seen in an<br />

inadequately drained retrofilled transformer?<br />

COMMENT (Dave Sundin): Limit the scope to new transformers.<br />

COMMENT (Claude Beauchemin): The scope should not limit in that way.<br />

QUESTION (Claude Beauchemin): Should synthetic esters be included?<br />

Page 63 of 160

QUESTION: The mineral oil guide is a definitive document. Should we even try to put together a separate<br />

guide for natural esters considering the lack of field data?<br />

COMMENT (CHAIR): A trial guide is an option.<br />

COMMENT (Fredi Jacob): Look at the practical alternative. Laboratories gather natural ester gas data and<br />

must interpret it for their customers. The interpretation is empirical and evolutionary.<br />

COMMENT (Michel Duval): The guide should give a strong warning that it’s based on laboratory data.<br />

QUESTION (Don Chu): Synthetic esters are used in transformers. Should the guide include synthetic<br />

ester?<br />

COMMENT (Claude Beauchemin): Synthetic and natural esters are more alike in their gassing behavior<br />

than synthetic esters and mineral oil.<br />

COMMENT (Michel Duval): There is enough information available to warrant combining synthetic and<br />

natural esters in one guide.<br />

QUESTION (Dave Sundin): Should we include synthetic esters if the main manufacturer does not<br />

participate in drafting the standard?<br />

COMMENT (Don Chu): The manufacturer will definitely not participate if synthetic esters are not<br />

included.<br />

COMMENT (Clair Claiborne): The manufacturer does not consider the US to be a significant market.<br />

COMMENT (Michel Duval): The behavior of the synthetic ester is more like manufacturer A’s natural<br />

ester than it is to manufacturer B’s natural ester.<br />

Amended Motion<br />

Claude Beauchemin moves to amend the motion to include synthetic esters. Don Chu seconds. The<br />

amended motion accepted by Don Cherry.<br />

Vote:<br />

For: 14<br />

Against: zero<br />

Motion as amended passed.<br />

Scope<br />

COMMENT (Bill Bartley): The scope proposed by the Task Force can be different than the scope adopted<br />

for the guide.<br />

QUESTION (Joe Cultrera): Do laboratory tests reflect what is actually happening inside the transformer?<br />

COMMENT (Fredi Jacob): Change “theory” to “interpretation”<br />

COMMENT (Michel Duval): In the course of writing this guide we may conclude that it should be an<br />

addition to the mineral oil guide.<br />

CHAIR: What is the difference between a trial use guide and a guide?<br />

COMMENT (Bill Bartley): Trial use is intended for things new to the industry, so it might be appropriate<br />

for this guide.<br />

COMMENT (Ge<strong>org</strong>e Reiter): An advantage of the trial use guide is that it makes users aware that this is<br />

new to the industry.<br />

QUESTION: Would a trial use guide make life easier for customers working with their insurance<br />

company?<br />

CHAIR: It would be unlikely that it would make a difference.<br />

QUESTION (Patrick McShane): Did the silicone gas guide start as a trial use guide?<br />

CHAIR: No.<br />

QUESTION (Patrick McShane): Has the silicone gas guide been changed since it was issued?<br />

8.6.3.3 WG C57.139 – DGA in LTCs<br />

Fredi Jacob-Chair, Sue McNelly – Secretary<br />

Sue McNelly, WG Secretary, presented a background review, and Rick ran the discussion. The WG<br />

meeting had 47 attendees. The officers called for more data. Fredi Jacob and Jack Harley are working on a<br />

warning statement for flammable gases in the LTC. More information is needed on where to include the<br />

warning in the guide.<br />

Claude Beauchemin stated that the PAR is set to expire end of 2009. Matt Ceglia of <strong>IEEE</strong> stated may be<br />

risk of requiring new par. Matt stated should work on ballot group by June. Bill Bartley stated that<br />

RevCon deadline date Oct. 19th. Jim Dukarm stated that the draft is ready and needs WG review for<br />

checking accuracy and for raising any issues before next meeting so it can be voted on for submittal at next<br />

meeting and immediate forwarding to <strong>IEEE</strong> SA.<br />

Review of Draft 9.1 of the guide:<br />

1) Information from Jim Dukarm on the LTC DGA samples was presented by the Chair.<br />

2) The following commentary was provided by Jim:<br />

a. For the gas concentration norms, the left one is the C0.95 norm as derived in Addendum<br />

A. The right one (enclosed in parentheses) is the corresponding outlier rejection limit U.<br />

See the text at the end of the gas concentration norm 'recipe' for some discussion of these.<br />

Spring, 2009 Meeting Minutes - Unapproved<br />

b. In Example 1, both the ethylene/acetylene and the hot-metal/acetylene ratios are normal<br />

right up to the last sample shown, where they have extreme values. In this example, the<br />

gas concentrations are so low in all but the last sample that the gas ratios would have<br />

been meaningless.<br />

c. In all samples, gas concentrations were well below their respective limits.<br />

d. In Example 2, the gas ratios remain low and relatively constant in all samples. The<br />

ethylene, total hot metal gas, and acetylene all become noticeably high in the last two<br />

samples. Here we notice the usefulness of the advice given in the statistical Addendum<br />

where it is stated that if the percent-point limit C0.95 for a combustible gas is drastically<br />

higher than the outlier rejection limit U, then U should be considered for use as the<br />

caution limit for that gas.<br />

3) The following comments from Jack Harley were discussed:<br />

a. Comment 1: The gas levels discussed at the last meeting were quite high. Explosion level<br />

for acetylene in air is 2.5% or 25,000 PPM. Should there be a safety warning about C2H2<br />

and the hot metal gases when readings get this high?<br />

i. TV indicated that it would be good to have a statement in the guide. Tom Prevost<br />

indicated that if you do, that you would need to set limits. The guide is for<br />

diagnostics. Comment from Dave Hanson was that anytime you are handling the<br />

fluid you need to be aware of the concern.<br />

ii. Fredi Jakob asked for a motion. TV Oommen proposed that a safety warning be<br />

included. There were inclusive results from the vote. Fredi explained that setting<br />

limits would be difficult as individual gas limits would be meaningless. Jack Harley<br />

asked the question of whether as the typical user would know that there was a risk of<br />

opening a unit with this type of concentration of acetylene. He was in favor of some<br />

type of warning.<br />

iii. Fredi Jacob indicated that a reference to the sampling guide be made. Beauchemin<br />

indicated that he didn’t feel this resolved the issue of the safety issue. Fredi asked<br />

Jack and Claude to propose some wording for the document. Jin Sim requested that<br />

they contact Paul Griffin from Doble for more information.<br />

Note: After the meeting, Fredi Jacob made a draft of the proposed warning for the WG to<br />

consider:<br />

Warning<br />

“Oil from load tap changers (LTC) taken while flushing prior to sampling or during and<br />

after removal for LTC servicing may create a flammable gas mixture when exposed to<br />

air. Handling of this oil should only be attempted by those maintenance or test<br />

technicians and engineers trained in working on and knowledgeable of the risks<br />

associated with it.<br />

Miami, Florida<br />

Page 66 of 160

Oil with gas levels exceeding 1500 ppm dissolved hydrogen or exceeding 10,000 ppm<br />

total dissolved combustible gases could create a flammable gas mixture when exposed to<br />

air.”<br />

b. Comment 2: What is the effect of gas solubility in oil on the readings? For example, if a<br />

field chromatograph is being used in the gas space, will the readings be the same as in the<br />

oil? And is there a saturation level for C2H2 or the hot metal gases in oil?<br />

i. Fredi Jakob indicated that the answer to this is no. There won’t be any agreement.<br />

The answer to the second part of Jack’s question is yes, there is a saturation level,<br />

but it is very high and would never happen. Jack indicated that the new automated<br />

methods of taking samples may be in the head space. Fredi indicated that most look<br />

at the gas-in-oil. A total combustible would be the only<br />

c. Comment 3: A sample spread sheet showing the formulae in the cells would be very<br />

helpful.<br />

i. Fredi Jacob will ask Jim Dukarm w provide the spreadsheet in the document.<br />

4) Comment 4: from Vijayakumaran Moorkath:<br />

d. “This standard is applicable only for oltc operating in mineral oil. There are LTCs<br />

operating in silicone oil and also natural ester. Are we planning to have a separate<br />

standard for these applications? Further, it is mentioned in cl.1.1 Scope, that the<br />

evaluation criteria is for mechanical damage or failure. I think the DGA should indicate<br />

initiation of dielectric failure of insulation components in diverter switch.”<br />

e. Response from Fredi Jacob: No, we will not be addressing silicone or natural ester fluids<br />

in this guide. It is too late to change the scope and they will have different values just as<br />

in the main tank.<br />

5) The latest draft, 9.1, was reviewed section by section with additional changes identified to be<br />

included in the next draft 10. The following items need to still be addressed:<br />

f. Clause 6.3.1 – Question on where did the code come from. Provide reference.<br />

g. Add THG and Hot Metal Gases to the list of definitions in clause 3.<br />

6) Fredi reviewed the case histories document.<br />

6. Comments from Jack Harley and Paul Griffin<br />

The <strong>IEEE</strong> Patent disclosure requirements were discussed and a request was made for disclosure of any<br />

patents that may be related to the work of the WG. There were no responses to the request for disclosure.<br />

Approval of minutes from the Fall 2009 meeting in Miami, Florida was requested. The minutes were<br />

approved as written.<br />

Due to a late start, introductions of attendees were not made.<br />

New Guide:<br />

A new PAR request will need to be filed to start over with an immediate revision to the guide to address the<br />

remaining issues that have been raised as soon as the ballot process with the existing document is complete.<br />

Proposed Scope (Revision text indicates changes to present Guide Scope language):<br />

“This guide applies to mineral-oil-immersed transformers and addresses:<br />

1. The theory of combustible gas generation in a transformer;<br />

2. The interpretation of gas analysis;<br />

3. Suggested operating procedures;<br />

4. Various diagnostic techniques, such as key gases, Dornenberg and Rogers ratios; Duval triangle;<br />

and other methods;<br />

5. Instruments for detecting and determining the amount of combustible gases present;<br />

6. Case studies;<br />

7. Evaluation criteria and guidelines; and<br />

8. A bibliography of related literature.”<br />

A motion to adopt the scope as proposed was made and seconded. The floor was opened for discussion.<br />

Mark Perkins asked if the Guide applies to high temperature transformers. If not, can it be expanded to<br />

include them. Tom Prevost indicated that his understanding is that it is for transformers containing only<br />

cellulose insulation. Then there is a question in what of windings not covered in cellulose or with nylon<br />

mesh instead of cellulose.<br />

One comment is that the standard deals primarily with the oil, for specific areas dealing with cellulose, they<br />

could be individually addressed within the document.<br />

Another comment was made that users with very small units will try to apply this Guide and it may or may<br />

not be appropriate.<br />

A question regarding expanding the Guide to include Natural Ester fluids was asked. The amount of work<br />

that is expected just to get the Guide revised for mineral oil alone is considerable. If the guide was<br />

expanded, this may make it difficult to get the Guide<br />

Don Platts requested an amendment to remove the word “and” from the end of item 7 in the Scope.<br />

The motion as amended was approved.<br />

Proposed Purpose:<br />

“The purpose of this document is to provide the transformer owner and/or operator with a Guide for<br />

evaluating transformers using analytical tools and methods involving transformer mineral oil and<br />

associated developed gases.”<br />

A motion was made and seconded to approve the proposed purpose.<br />

A question was asked as to whether the intent is to include both operating and stored units. This is not the<br />

purpose of the guide, but would not now preclude it.<br />

It was pointed out that the word “operating” is used in the Scope that was just approved.<br />

Tom Prevost indicated that the wording of the Scope and Purpose is critical to moving forward with a PAR<br />

request, so it is necessary that we get this right.<br />

An amendment was made to modify the wording by changing the word “transformers” to “transformer”<br />

and add the word “condition”.<br />

The motion was made to accept the above changes and the motion was approved.<br />

8.6.3.5 TF Guide for Field Application of Natural Esters<br />

Jim Graham – Chair, Jerry Murphy Vice-Chair<br />

Jim Graham presented the TF task force meeting summary to the subcommittee based on the minutes<br />

below. There were 42 attendees. Jim requested reviewed the meeting highlights covered in the meeting<br />

minutes below. Most important, a consensus was reached to recommend a Guide be established. Jim asked<br />

for and received from the Chair approval to upgrade the activity status from a TF to WG level and draft a<br />

PAR. The approval was received.<br />

TF meeting minutes as received:<br />

Meeting Minutes / Significant Issues / Comments:<br />

The meeting was called to order at 3:15 PM, introductions were made, and an attendance roster was<br />

circulated. Membership attendance was checked, and we did have a quorum. The chair asked the group if<br />

there were any patents that needed to be disclosed. None were announced to the group. The task force<br />

minutes from the Fall 2008 meeting were reviewed and approved.<br />

The proposed scope and purpose were presented and reviewed for additional comments. Most of the<br />

comments centered on the words to be consistent with the subcommittee O&P manual. The group also<br />

decided to change the word fluid/fluids to liquid/liquids throughout the document.<br />

The task force members gave a consensus decision to submit a recommendation to the subcommittee for<br />

establishing a working group. The intent is to submit a title, scope and purpose for subcommittee and main<br />

committee consideration.<br />

A draft outline was discussed as a starting point should a working group be formed. Don Cherry and<br />

Patrick McShane offered to provide information for inclusion in the draft outline.<br />

The meeting adjourned at 4:15.<br />

8.6.3.6 <strong>IEEE</strong> C57.130 <strong>IEEE</strong> Trial-Use Guide for Dissolved Gas Analysis During Factory Temperature Rise Tests for<br />

the Evaluation of Oil-Immersed <strong>Transformers</strong> and Reactors.<br />

No WG meeting was held in Miami. Rick Ladroga asked if anyone knew the current draft number. An<br />

attendee responded 17 is the most recent draft. No specific information was provided on the status from the<br />

ballot resolution committee. Further specific action was not determined. The PAR is set to expire by the<br />

end of 2009.<br />

This Task Force was established after the spring 2008 meeting to investigate the issue and determine if<br />

there is a need to develop a standard for particulate limits for new fluid, as received in new equipment, and<br />

continued use. No TF meeting was at the spring 2009 meeting.<br />

8.6.4 Old Business<br />

An Ad Hoc committee formed to review existing standards to determine the consistency of terms regarding<br />

dielectric coolant terms used in TC Standards. John Luksich did the first draft of listing the greater than 60<br />

standards that make at least one reference to “oils”. More input sought and Bill Bentley suggested that the<br />

topic be presented to the Standards SC meeting later in the day. Patrick McShane agreed to make the<br />

presentation in order to get guidance from the TC Standards SC.<br />

8.6.5 New Business<br />

The Chair of the TC Standards SC, William Bartley advised that <strong>IEEE</strong> C57.121 – Guide for Acceptance<br />

and Maintenance of Less Flammable Hydrocarbon Fluid in <strong>Transformers</strong> is set to expire. David Sundin<br />

offered to volunteer to work on getting the process on track.<br />

It was requested that a new TF be developed to continue the work done by the TF that was started in the<br />

Insulation Life SC on moisture in insulation. It was determined by the ILSC that this more appropriately<br />

belonged within the IFSC. Bob Raser volunteered to chair this TF. Tom Prevost, Paul Boman, Matt<br />

Kennedy, Jim Thompson, Don Platts, Hali Moleski, and Rick Ladroga also volunteered to work on this TF.<br />

Introductions of members and guests were made.<br />

Approval of minutes from the Fall 2008 meeting in Porto, Portugal was requested. The<br />

minutes were approved as written.<br />

The <strong>IEEE</strong> Patent disclosure requirements were discussed and a request was made for<br />

disclosure of any patents that may be related to the work of the WG. There were no responses<br />

to the request for disclosure.<br />

Chair’s Comments – The Chair, Tim Reynolds has stepped down from his position. The Vice<br />

Chair Carlo Arpino has indicated a desire to continue, but not to take over the WG. We are<br />

looking for someone to step forward to take the Chair position to see this guide through to<br />

ballot.<br />

Draft 5.2 of the Guide has been posted. This draft has cleaned up formulas and moved<br />

symbol definitions into an Annex. There have been many changes and reversals of changes to<br />

the Guide. At this point, it is uncertain whether the present draft represents all of the votes<br />

taken in the past. Don Duckett volunteered to review the Guide and compare to past minutes<br />

documenting decisions. However, after the meeting, Don agreed to take over as WG Chair,<br />

and will likely be looking for someone to help with this task.<br />

There are some oversights in the document that need to be resolved and found before the<br />

Guide is sent to ballot. At some point it was decided to take the cooling classes definitions<br />

and put in the Guide. The equations need to be reviewed to make sure they are in the correct<br />

location and have the correct definitions and terms.<br />

Juan Castellanos volunteered to review Annex G. Kurt Robbins volunteered to review the<br />

Clause 7 equations.<br />

Plan to meet the year-end deadline – The WG members will receive an e-mail regarding<br />

review of the document in a very short time. Those members not responding may be removed<br />

as members of the WG.<br />

Barry Beaster, Jin Sim, Rick Marek, and Dave Wallach volunteered to help go through<br />

comments received to resolve any issues identified.<br />

The question of gas evolution during overloads raised<br />

Loading recommendations based on loading – Jin Sim indicated that at one time there was a<br />

plan to add something to the Guide to address this. Clause 12.2, Limitations, has some<br />

information on this subject. There is no background material to support the information in the<br />

document, only what is thought to be values due to prudent practice. Don Platts indicated that<br />

he thought that we had decided to take this out since there is no background data to support<br />

the numbers. Jin Sim asked if by show of hand, how many members would vote negative if<br />

this was left as shown. There were a few more users present that did not vote to take the<br />

information out than negatives, however, there were enough that would vote negative that it<br />

would be difficult to resolve during ballot.<br />

Dave Wallach suggested possibly revising the section to take out the tables, but provide some<br />

language discussing the issue. Dave Wallach volunteered to take on rewriting this section.<br />

Clause 7.1 item 2) – Don Platts asked if there were any recommendations on whether the<br />

thermal decomposition of insulation during overload really generates bubbles in the oil.<br />

There were no comments.<br />

The meeting was adjourned at 10:05 am.<br />

The working group met on Monday, April 20, 2009 at 11:00 AM with 24 members and 100<br />

guests attending, with 9 guests requesting membership. This brings the number of members<br />

to 84.<br />

- Discussion of life curves – finite number vs. separate life curve for each possible<br />

combination.<br />

- Blended materials (such as upgraded kraft, wire enamels etc.) how to deal with<br />

- Test duration discussion (accuracy of testing)<br />

- Oil Temperatures/Oil preservation<br />

- Other issues, such as end-of life criteria, how to evaluate other types of materials<br />

thermally (such as bonded CTC, etc.). This section provided the most feedback, as<br />

there was a spirited discussion whether the end of life (for non-kraft materials)<br />

should be 50% tensile or some lower number – since 200DP for kraft seems to<br />

correlate to a lower number than 50% tensile (based on testing and our own<br />

standards requirements.<br />

8.7.3.2.6 “Industry Proven System”<br />

The chair mentioned that the more precise the method, potentially the more complicated, and<br />

the more doubtful the method would be used. He offered a “carrot” to the group, that<br />

perhaps, due to the 40+ years of successful use of thermally upgraded kraft papers, one could<br />

develop a “Industry Proven System” which was by definition defined as meeting our 65C rise<br />

curve, assuming all of the conditions of the system were met, such as nitrogen content of the<br />

paper, type of processing, maximum operating temperature, etc. This could then allow all<br />

manufacturers to have access to a system without testing, and then our job would be to then<br />

perhaps define under what conditions a new test would be required and/or a reduced set of<br />

tests (one or two point comparison test).<br />

8.7.3.2.7 Comments<br />

The chair then finished up the discussion by soliciting comments (one more time). After<br />

receiving little comments, the chair described the process. He will send the working group<br />

these minutes and the presentation, and then ask for feed back on the issue areas and<br />

proposals, and to have the feed back by the end of May. Once this has been received, the<br />

chair will develop a draft for submission to the working group in June.<br />

Projects:<br />

TF – Sub-clause 11.2.2e<br />

The TF is addressing two scenarios that could possibly result in hot-resistance time data not<br />

being suited to fit an exponential decay curve:<br />

1. The time constant of small distribution transformers may be short due to transformer<br />

thermal characteristics and measuring equipment<br />

2. The mean oil temperature surrounding the winding and the actual location of the winding<br />

may result in top and bottom oil temperatures not giving the intended average winding oil<br />

temperature.<br />

Juan Castellanos shared an example wherein the radiator configuration resulted in a decay<br />

curve that was not an exponential decay when related to measured average oil temperature.<br />

Barry Beaster applied the Blume methodology to Juan’s data determining hot-resistance at<br />

time zero. Juan commented that the average temperature of the oil at time infinity can be<br />

varied from 36.6 to 49.6 °C and still get a good data fit, but the resulting average winding<br />

temperature would be significantly different. He also commented that the 2 nd order<br />

polynomial approximation would give only one possible solution when using the least squares<br />

regression method. Bertrand Poulin commented he will share with the WG an iteration<br />

method not subject to human manipulation - in order to run again same data.<br />

Marcel Fortin gave a presentation on “Transformer Coil Average Temperature.” From<br />

examples of distribution transformers, Marcel concluded that measurement of the oil<br />

temperature surrounding the coils cannot be done sufficiently precise to serve as an<br />

extrapolation reference for the coils cooling curves. Correct interpolation of coils<br />

temperatures at time zero requires approximation of the coil and bulk oil time constants, and<br />

coil resistances measured in a short period compared to the coil time constant. Marcel<br />

proposes first measurements be taken in less than half the coil time constant and<br />

measurements extend to not much less than the coil time constant. Actual loading or the back<br />

to back method would be the preferred way to perform the heat run tests. Multiple<br />

interpolations are required to determine the best fit first order exponential coil cooling curve.<br />

Sanjib Som proposed coordinating efforts with IEC and will provide the Chair documents for<br />

cooling curve methodology.<br />

Oleg Roizman gave a presentation on “Temperature Rise Tests” illustrating some of the<br />

factors that affect winding temperature rise of power transformers. His findings supports some<br />

of the proposals the WG has completed for 11.2.2 such as recording hot resistance-time data<br />

points at 15-second intervals for power transformers and taking the first hot resistance data<br />

point no later than 4 minutes after shutdown. Other conclusions such as a longer data<br />

collection period for power transformers as for some cases with low time constant<br />

measurement at 4 minutes may be too long wait, and measuring one winding phase differ than<br />

the WGs completed proposal. He also gave recommendations for when using fiber optics<br />

temperature sensors inside windings.<br />

TF – Modified Temperature Test<br />

The TFs objective is to specify the parameters for a loading test, sometimes referred to as a<br />

quality control heat run, to check the transformer when a full temperature test has not been<br />

performed. Mark Perkins gave the following report.<br />

The Task Force met Sunday April19, 2009 at 1:30 pm with Subhash Tuli, Paulette<br />

Payne Powell, Don Platts and the Chairperson, Mark Perkins present. The TF<br />

discussed different ways that this modified temperature test might be included in the<br />

standards:<br />

1. The modified temperature test could be listed as an "other" test in C57.12.00 and<br />

described in a sub-clause of Section 11 of C57.12.90<br />

2. A working group paper could be written describing the test and it could be included<br />

as a reference to C57.12.00 or C57.12.90<br />

3. C57.119 could have the title and scope changed to include the test in that guide.<br />

4. The test could be included as an informative Annex to C57.12.00 or C57.12.90 or<br />

C57.12.10.<br />

The TF was in favor of alternative 1. Don Platts agreed to take it forward to the<br />

Administrative Subcommittee for guidance.<br />

The TF reached consensus on what would be included in the modified temperature<br />

test:<br />

The modified temperature test is an” other” test used to verify the performance of the<br />

transformer when a full temperature test is not performed. Only one test is performed<br />

and that is done at the maximum nameplate MVA rating. The selection of tap changer<br />

positions, measurement points and setup parameters is made on the same basis as the<br />

normal temperature test at the tap position giving the highest average winding<br />

temperature rise as specified in C57.12.90 sub-clauses 11.1-11.6.<br />

The current in the transformer shall be the total loss current as defined in C57.12.90<br />

sub-clause 11.5. This current shall be held for a minimum of eight hours, of which a<br />

minimum of six hours must be at a top oil temperature rise above 80% of the<br />

calculated value. After this minimum duration, the top oil rise, bottom oil rise and<br />

average oil rise are to be calculated prior to shutdown. The average winding<br />

temperatures are to then be measured after shutdown as described in C57.12.90 subclause<br />

11.3, only at the total loss current.<br />

The average winding temperature gradients of additional windings are to be<br />

measured by circulating current corresponding to the maximum nameplate ratings of<br />

the windings for one hour followed by the average winding temperature measurement<br />

as described in sub-clause 11.3. The measured winding temperature rise values are to<br />

e adjusted for the maximum nameplate currents and for any other adjustments per<br />

clauses 11.2 - 11.6.<br />

Oil samples for dissolved gas in oil analysis are to be taken before and after the<br />

modified temperature test.<br />

The estimated top oil rise and average winding rise (based on readings taken<br />

immediately before the shutdown) are to be determined. If any of these values exceed<br />

the 65 degree limit, then a full temperature test is required.<br />

After the working group approves the proposed wording, a survey will be sent to the<br />

sub-committee. The next meeting of the TF will be Fall 2009 in Chicago at 1:30 pm<br />

on Sunday.<br />

The meeting adjourned at 2:40 pm.<br />

Unfinished Business:<br />

There were no items discussed.<br />

New Business:<br />

11.2.2b - Juan Castellanos proposes for power transformers that a series of hot resistance<br />

measurements made on "all terminal pairs" only apply to the maximum capacity heat run. For<br />

the minimum capacity heat run just one phase per winding would be required as there is no<br />

value added in testing all three phases at minimum or intermediate capacities. This proposal<br />

will be drafted and sent to the WG for straw ballot.<br />

11.2.2d Steve Snyder gave a presentation on “10- Minute Cooling Curve” for which<br />

measurements were made on both a 50kVA and 250kVA single phase distribution<br />

transformers using the short circuit and loading back methods.<br />

Steve said that as the coils are of small mass, the winding temperature rapidly approaches the<br />

surrounding oil temperature, and then the heat release rate declines as this temperature<br />

differential is reduced. Performing regression analysis on the entire 10-minutes of data can<br />

result in the constant-slope portion of the curve significantly influencing the time zero<br />

intercept producing less accurate results. The curve slope is much greater in the first time<br />

interval (0 – 3 minutes), which he believes most accurately reflects the winding temperature<br />

decay, and hence leads to the most accurate projection of the “time zero” value. Steve<br />

proposes for the distribution class transformers, that it is more appropriate to specify a<br />

minimum number of points e.g. 10 points collected over a certain time interval e.g. no longer<br />

than 30-second intervals.<br />

Marcel Fortin agreed to merge his and Steve Snyder’s presentation proposals into one<br />

proposal for a straw ballot by the WG.<br />

Being no other business, the meeting adjourned at 12:05pm.<br />

8.7.3.4 Task Force on High Temperature <strong>Transformers</strong> – Richard Marek<br />

The second meeting of the WG took place on Monday, April 20, 2009 in Concerto C/D<br />

Meeting Room at 3:15 pm, at the Hilton Downtown Miami; Miami, Florida, USA<br />

There were 16 members and 30 guests present. Introductions were made and attendance<br />

sheets were circulated. The <strong>IEEE</strong> patent policy was discussed and there were no concerns<br />

regarding patents.<br />

Vice-Chair Waldemar Ziomek was introduced.<br />

The Chairman informed the group that the PAR request was approved by NESCOM on 18<br />

March 2009, and is valid until December 2013. The project has been assigned the number<br />

PC57.154. The approved title, scope and purpose were shown to the group. There were no<br />

comments concerning the title or purpose.<br />

The Chairman noted that draft 2 incorporates comments by members Bill Henning and Patrick<br />

McShane and he reported briefly on the outside working meeting which was held on Sunday,<br />

April19. He noted that there will be a second working meeting on Thursday, after the normal<br />

meetings are finished. The purpose of these meetings was to allow time to review and modify<br />

the draft which had been proposed as a starting point at the previous meeting in Porto. This<br />

draft was similar to an IEC document, modified to fit the <strong>IEEE</strong> template. During this Sunday<br />

meeting, modifications to the scope were suggested. It was also decided that section 4 should<br />

be moved to an informative annex, since it was considered tutorial.<br />

Discussion about the scope in the WG meeting triggered a question as to which transformers<br />

are excluded from the scope or does it include all units? The Chair stated that his intention<br />

was to include all transformers, but that the WG should make this decision. The members<br />

were requested to provide comments to the chairman concerning revision to the scope, after<br />

which a decision on the request for revision will be made before the next meeting.<br />

Marion Jaroszewski stated that the mobile transformers do not always conform to the<br />

requirements of the C57.91 loading guide and that some care is needed to avoid confusion.<br />

Don Platts expressed concern about the status of the proposed document, questioning whether<br />

it was really a guide rather than a standard. He suggested that maybe it would be better to use<br />

<strong>IEEE</strong> C57.12.00 as a template, modifying as necessary to make sure it was a standard. The<br />

Chairman disagreed stating that the WG should be able to modify the draft to comply with the<br />

PAR.<br />

Claude Beauchemin asked the WG if anyone has any information or study results concerning<br />

bubble generation with high-temperature insulation. Mike Franchek said he thought<br />

Weidmann had performed some research many years ago and that he would try to make it<br />

available to the WG.<br />

Draft 3 is expected to be circulated before the fall meeting. The WG was requested to review<br />

the draft 2 document and make comments or suggestions which would be incorporated into<br />

draft 3.<br />

Unapproved Meeting Minutes – Miami, FL – April 22, 2008<br />

� A proposed rewording of Section 7.1.4, Three phase transformers with<br />

inaccessible neutrals, was presented by M. Perkins. There were three<br />

points of discussion:<br />

• The criteria of 0.5% tolerance on ratio may not be sufficient to identify<br />

a turn-to-turn short if there are a large number of turns.<br />

• The current standard specifies a method different than described, both<br />

methods should be included.<br />

• The figure associated with this new method was clarified by adding the<br />

phase description for each of the measurements.<br />

• Following discussion, it was decided to include both methods of testing<br />

in Section 7.1.4. It should be noted that the user would need to request<br />

using the proposed method in order to get data that could be field<br />

verified.<br />

� The revised Sections 6 and 7, including the new proposed method for<br />

measuring the ratio of three phase transformers with inaccessible neutrals,<br />

will be sent out for a survey of the Performance Characteristics<br />

Subcommittee. This was sent out after the meeting.<br />

• A proposal to include a description of measuring ratios using the capacitance<br />

bridge method had been made at the F2008 meeting in Porto. The proposed<br />

wording was not available. This item will be carried to F2009.<br />

Unapproved Meeting Minutes – Miami, FL – April 22, 2008<br />

The chairman presented an update on the C57.12.00 ballot. Dong Kim is working<br />

to address a number of comments from the original ballot, and the first<br />

Recirculation ballot should come out soon.<br />

New Business<br />

A. WG Item 86 for C57.12.00 - 2006 Table 10 Nameplate Information, and<br />

Section 8 – Testing and Calculations<br />

A change was requested from the Distribution <strong>Transformers</strong> Subcommittee to add<br />

a new requirement for distribution transformer nameplates to state “DOE<br />

Compliant” for such transformers, and also add a statement in the Certified Test<br />

Data Section 8.6.<br />

After an introduction and explanation of proposed changes by Mr. Stephen Shull,<br />

a discussion followed within the Working Group that resulted with a motion to<br />

accept the final wording for addition to Table 10 Nameplate Information and an<br />

addition to Sect. 8.6 Certified Test Data. The motion was approved unanimously.<br />

The chair will forward this request to Dong Kim for insertion into the C57.12.00<br />

Recirculation Ballot.<br />

New text for Table 10 in 5.12.2 Nameplate information:<br />

“ 24 DOE Compliant (13) DOE Compliant (13) DOE Compliant (13)<br />

NOTE 13—The nameplate of transformers that must comply with 10 CFR Part<br />

431 shall include this statement [“DOE Compliant”], when the transformer is to be<br />

used in the United States or one of its protectorates or territories. <strong>Transformers</strong><br />

that must meet this Code of Federal Regulation are defined in 10 CFR 431.192.”<br />

Addition to 8.6 Certified test data :<br />

“17) DOE Compliant 7<br />

18) Other special test results (when specified)*.<br />

NOTE 7—If this transformer is to be used in the United States or one of its<br />

protectorates or territories and is required to comply with 10 CFR Part 431, this<br />

phrase [“DOE Compliant”] shall be included. <strong>Transformers</strong> that must meet this<br />

Code of Federal Regulation are defined in 10 CFR 431.192. At the discretion of<br />

the user, the actual calculated efficiency value may be substituted for this phrase.”<br />

B. Paragraph for C57.12.00 on Winding Resistance Measurement of Stabilizing<br />

Windings.<br />

Having studied the best manner to implement this request in C57.12.00, the<br />

chairman remarked that it appears the requirement to conduct this testing is<br />

already included within Table 18 (test requirements), but could be expanded upon<br />

in section 8.7. Therefore, the Chairman proposed changes in Section 8.7<br />

Certified Test Data, as follows:<br />

“C) Test and calculated data (by individual serial number ; if the results are<br />

from…)<br />

2) Winding resistances, including stabilizing winding when two external terminals<br />

are available.”<br />

The new statement was approved unanimously, including the clarification of<br />

applying this requirement only for Stabilizing Windings that have two external<br />

terminals available.<br />

C. WG Item 82, Clause 7.1.4.4 Stabilizing Windings- TF Report and discussion<br />

The chairman of TF Stabilizing Windings presented a new (second) progress<br />

report, including the new working version for Clause 7.1.4.4 of C57.12.00:<br />

“7.1.4.4 Stabilizing Windings.<br />

Stabilizing windings in three-phase transformers (Delta-connected windings with no<br />

external terminals) shall be capable of withstanding the transient current duty resulting<br />

from any of the system faults specified in 7.1.1, recognizing the system grounding<br />

conditions as stated in user’s spec. In case users do not specify system grounding<br />

conditions, including system zero sequence impedance and type of grounding<br />

intended for the transformer or autotransformer, system impedances per <strong>IEEE</strong><br />

C57.12.00 shall be assumed, as well as solid grounding connection for neutrals of<br />

main windings.<br />

If users specifiy impedances from stabilizing winding to main windings, the<br />

manufacturer shall provide the appropriate stabilizing winding kVA and voltage. If<br />

stabilizing winding impedances are not specified, the manufacturer shall provide<br />

appropriate impedance from design, in order to withstand thermal and mechanical<br />

effects resultant from transient operating currents.”<br />

---- Loading Part (Paragraph on Section 5?)<br />

“Stabilizing windings shall be designed to withstand continuous thermal duty of the<br />

circulating current resulting from temporary load and or voltage imbalance on the<br />

main windings, as specified by the user. Load currents and supply voltages should be<br />

specified in magnitude, angle and duration, to allow verification of compliance with<br />

maximum allowable temperatures according to C57.12.00.<br />

In the event no continuous thermal duty for the stabilizing winding can be established<br />

from the user´s spec, the manufacturer will use as stabilizing winding continuous kVA<br />

a fraction of the transformer´s main rating, as resultant from a full single phase load in<br />

the main secondary winding (33.3% of transformer’s three phase rating) and infinite<br />

bus supply from the primary winding.<br />

The manufacturer shall prepare transient and permanent loading calculations for<br />

stabilizing windings, in order to demonstrate adequacy to requirements established in<br />

foregoing clauses.”<br />

---- Name Plate Part<br />

“Internal reactors used to supplement stabilizing winding impedances to main<br />

windings, shall be included in the nameplate. ”<br />

An important insight resulting from the work of the TF Stabilizing Windings is that<br />

Stabilizing Windings cannot be specified the same way as Tertiary Windings, as<br />

the Stabilizing Windings cannot be subjected to conventional three phase loads.<br />

Further input from users is requested to clarify the maximum expected thermal<br />

loading for Stabilizing Windings, or expected current and voltage imbalance in<br />

service (magnitude and duration).<br />

As next steps, the members of the TF Stabilizing Windings will continue to<br />

evaluate and assimilate feedback to refine the proposed new wording. The Task<br />

Force also believes there is sufficient interest in this subject to conduct a<br />

tutorial/informational session at an upcoming meeting.<br />

The Working Group met on Tuesday, April 21, 2009 at 3:15 PM with 7 members<br />

and 5 guests present. Sheldon Kennedy chaired the meeting.<br />

The <strong>IEEE</strong> disclosure statement was discussed. There were no patents pertaining<br />

to this standards work for which any members had awareness.<br />

The minutes of the October 7, 2008 meeting in Porto were approved.<br />

The Chair announced that the Amendment, C57.18.10a had been approved and<br />

published in March 2008. The Errata was produced by <strong>IEEE</strong> in 2006. Along with<br />

C57.18.10 we now have these three documents as a group. C57.18.10 expired in<br />

2008 and was sent out as a Reaffirmation Ballot. The Reaffirmation ballot of<br />

C57.18.10 along with the Errata and the Amendment, C57.18.10a were included<br />

as a group. This ballot passed with no negative votes and only one affirmative<br />

comment. The standard, amendment and errata were sent to REVCOM and<br />

approved.<br />

There was a discussion about the standards being written in the Vehicular<br />

Transportation Society of <strong>IEEE</strong>. A traction rectifier transformer standard, rectifier<br />

standard and many C37 switchgear standards are being revised by this<br />

<strong>org</strong>anization with emphasis on the needs of the transit and rail industry. Concerns<br />

about duplication of standards and conflicts in the standards were raised.<br />

The chair announced that the IEC Converter <strong>Transformers</strong> for Industrial<br />

Applications IEC 61378-1 standard is under revision again.<br />

The Working Group has completed its task. There is interest in keeping a Task<br />

Force to work on a few special items while we still have the group together. Phase<br />

shifted secondary windings with multi-pulse secondary windings such as 18 pulse,<br />

24 pulse, 36 pulse, 48 pulse and 54 pulse are becoming a great part of the motor<br />

drive transformer applications. There is no discussion about these in the present<br />

C57.18.10 and this will need some work. Electrostatic ground shields are not<br />

discussed in the present standard and there is interest in keeping abreast with the<br />

Vehicular Transportation rectifier transformer standard and the IEC Converter<br />

Transformer standard so that we harmonize with them. There may be some other<br />

items that members would like to work on before we try to do a full revision of the<br />

original 1998 document, which will need a great deal of work to bring to the newer<br />

formats. The Working Group would like to survey the Rectifier Transformer<br />

Working Group, the Performance Characteristics Subcommittee and the Dry Type<br />

Subcommittee for interest in forming and joining the task force and any other<br />

items that may need to be worked on by this proposed Task Force.<br />

8.8.4.6 WG on “<strong>IEEE</strong> Standard Requirements, Terminology, and Test Procedures<br />

for Neutral Grounding Devices”, PC57.32 – Steve Schappell, Chairman;<br />

Peter Balma, Vice-Chair<br />

The Neutral Grounding Devices working group was called to order at 9:35 AM on<br />

April 21, 2009 and introductions were made. There were 15 attendees, 6<br />

members, 7 guests, and 2 requesting membership. The minutes from the March<br />

18, 2008 meeting in Charlotte, North Carolina were approved (a meeting was not<br />

held in the Fall of 2008), and copies of the minutes and Draft 6 of the standard<br />

were distributed.<br />

1. <strong>IEEE</strong> patent policy was reviewed and the group was asked if there were any<br />

disclosures. There were none.<br />

2. PAR status was reviewed and indicated that a PAR extension was requested<br />

and approved, and that it will expire 12/31/09.<br />

3. The working group then proceeded to review Draft 6 of the document, and the<br />

following salient points were discussed:<br />

a. The normative references have been reduced to two, and the definitions<br />

are complete.<br />

Performance Characteristics Subcommittee<br />

Unapproved Meeting Minutes – Miami, FL – April 22, 2008<br />

b. Clause 4, Service conditions, was discussed, as the clause does not<br />

include lower temperature limits. After review, the group decided to refer<br />

the user of the document to the appropriate piece of equipment and to add<br />

values for resistors. This information will be presented in a table.<br />

c. The clause describing the “K” multiplier for peak asymmetrical current will<br />

be modified to include an equation and table for the general application of<br />

neutral grounding devices, and to add a paragraph and equation to the<br />

clause indicating that the application of grounding devices at or near<br />

generators or large motors may require a modified “K” multiplier.<br />

d. The current document utilizes the concept of Insulation Class throughout<br />

the document, after review and discussion, the group decided to change<br />

this to Nominal System Voltage. The next draft will be revised to reflect<br />

this.<br />

e. The group agreed to update the Dielectric Test Voltage table to include all<br />

devices, and to update its contents to match current equipment standards.<br />

The new table will also indicate non-standard voltage classes so the group<br />

can review classes to be eliminated.<br />

f. After discussion, it was decided that the Limiting temperature table will be<br />

updated to reflect a 40°C ambient temperature, and to reflect 65°C rise<br />

transformers (Table 7 of this clause will also be updated to reflect 65°C<br />

rise).<br />

g. The temperature coefficient of resistance for neutral grounding resistors<br />

will be changed to 0.0002800. This coefficient reflects a 20% change in<br />

the nominal resistance over the operating temperature range for resistors.<br />

h. It was proposed to modify the Insulation Classes table, (Table 6, column<br />

4), for fault voltage criteria for resistors. Sergio Panetta will draft values<br />

for resistors and/or revisions to the associated clause for resistors.<br />

i. The group decided to remove the Capacitor clause from the standard, as a<br />

review of the industry did not find applications of Capacitor ground<br />

devices. This will require a modification of the existing PAR, as it is a<br />

change in the scope for this standard.<br />

j. Instead of developing a table for test requirements of Combination<br />

grounding devices, the user will be referred to other devices in the<br />

standard, and that the user and manufacturer should agree on the tests to<br />

be performed.<br />

k. All equations in the standard will be revised to reflect Metric units.<br />

4. In old business, Richard Dudley asked if the material on ground fault<br />

neutralizers was available. As it was not, he indicated he would supply the<br />

material to the group.<br />

<strong>IEEE</strong> guides for the application of grounding, i.e. the C62.92 series.<br />

8.8.4.7 PCS WG on “Guide for the Application and Interpretation of Frequency<br />

Response Analysis for Oil Immersed <strong>Transformers</strong>”, PC57.149 –– Chairman;<br />

Charles Sweetser<br />

WG PC57.149 met for the development of the Frequency Response Analysis<br />

(FRA) Guide in Miami, FL on April 6, 2009 at 1:45 PM. There were 84 people in<br />

attendance. The FRA Working Group meeting was called to order at 1:45 PM.<br />

The first order of business was to show five slides regarding patents, assurances<br />

and inappropriate behavior. The minutes from the Porto, Portugal 2008 meeting<br />

were approved by unanimous vote.<br />

Working Group Chair Update<br />

Draft 6 was presented to the Working Group, which now includes the Analysis<br />

and Interpretation Section. Draft 6 is expected to be internally circulated within the<br />

Working Group for a pre-ballot trial.<br />

The Working Group Chair presented a brief report on what had been done in the<br />

last six months. It was estimated that the document is over 95% complete. The<br />

latest contributions were identified and discussed. It included the following<br />

sections.<br />

Edits to Section 5: Analysis and Interpretation - The discussions focused on<br />

failure modes and related case studies.<br />

The following contributions regarding failure modes were presented:<br />

1. Radial “Hoop Buckling” Deformation of Winding<br />

2. Axial Winding Elongation “Telescoping”<br />

3. Overall- Bulk & Localized Movement<br />

4. Core Defects<br />

5. Contact Resistance<br />

6. Winding Turn-to-Turn Short Circuit<br />

7. Open Circuited Winding<br />

The discussion focused on how various failure modes affect the following<br />

frequency ranges: 20 Hz – 10 kHz, 5 kHz – 100 kHz, 50 kHz – 1 MHz, and > 1<br />

MHz.<br />

During the failure mode discussion, the Greg Anderson indicated that the effect of<br />

the reversing switch position be mentioned.<br />

The Working Group chair ask the member for any additional failure mode data<br />

regarding floating shields and core defects, especially unintentional core grounds.<br />

Paulette Payne, Peter Werelius, Alexander Kraetge, Ge<strong>org</strong>e Frimpong, Larry<br />

Coffeen, Greg Anderson, Anthony McGrail, and Alan Darwin volunteered to<br />

review the new contributions to the Analysis and Interpretation Section.<br />

Other Comments<br />

Required versus Optional Test. As a follow-up to the concern raised at the<br />

Proto meeting, the Working Group discussed “required versus optional tests.”<br />

Several members voiced their concern that there are some transformer<br />

designs that quickly go over 18 tests. The feeling is that this may be too time<br />

consuming and may be unnecessary. The importance of the open circuit and<br />

short circuits tests were discussed. All Working Group members agreed with<br />

the requirement of performing open circuit tests on all available windings. A<br />

few members stated perceived limitations with performing short circuit tests,<br />

however, other expressed high value. The guide will consider both the open<br />

circuit and short circuit tests to be required.<br />

8.8.5 Old Business<br />

Alexander Kraetge requested that the FRA Working Group investigate the<br />

possibility of adopting a universal data format. This may be difficult because<br />

information used to link the file to other diagnostic tests may be included in the<br />

FRA file. The Working Group agreed to re-open this discussion at the next<br />

meeting.<br />

None<br />

8.8.6 New Business<br />

Ramsis Girgis announced that he was resigning as Chair of the Performance<br />

Characteristics Subcommittee. He has been Chair for 6 years. He will continue<br />

to attend the <strong>Transformers</strong> <strong>Committee</strong> meetings, and wants to focus on the WG<br />

under Audible Sound & Vibration.<br />

Ramsis announced that Stephen Antosz will take over as Chair, after this<br />

meeting.<br />

A thank you from the membership was given by a hearty round of applause.<br />

8.9 POWER TRANSFORMERS – TOM LUNDQUIST, CHAIRMAN<br />

The Power <strong>Transformers</strong> Subcommittee met on Wednesday, April 22, 2009 at 1:30 p.m.<br />

with attendance of 157; comprised of 65 members and 92 guests.<br />

The minutes from the Fall 2008 meeting in Porto, Portugal were approved with no<br />

changes.<br />

The chairman asked if anyone was aware of any patent conflicts, none were voiced.<br />

8.9.1 WORKING GROUP AND TASK FORCE REPORTS<br />

8.9.1.1 TASK FORCE FOR REVISION OF C57.17, REQUIREMENTS FOR ARC<br />

FURNACE TRANSFORMERS – Dominico Corsi, Chairman<br />

No meeting held. The document was sent to the editor for comments. Any needed<br />

changes will be made and then it will be sent out for ballot.<br />

8.9.1.2 WORKING GROUP FOR DEVELOPMENT OF PC57.143, GUIDE FOR<br />

APPLICATION OF MONITORING TO LIQUID IMMERSED TRANSFORMERS<br />

AND COMPONENTS – Donald Chu and Andre Lux, Co-Chairmen<br />

Meeting started shortly after 8 AM. There were a total of 98 attendees, 42 members<br />

and 56 guests.<br />

Status update presented:<br />

Ballot pool has been established.<br />

Document is presently out for ballot with ballot closing May 14.<br />

The document that was circulated for ballot was Draft 20 as it existed at our last working<br />

group meeting. Since that time, one section had been rewritten by a group of 4<br />

members working collaboratively to resolve issues in the section. This revised section<br />

should have been inserted to replace the content in Draft 20 prior to balloting. Since it<br />

was not, the new section will be emailed to the working group this week and it will be<br />

merged into the document for the first re-balloting round.<br />

Eight (8) volunteers signed up to assist by participating as part of the ballot resolution<br />

group. Their efforts will commence after the ballot closure of May 14.<br />

Meeting adjourned at 8:40 AM.<br />

Page 92 of 160

The working group met at 11:00 a.m. on Monday, April 20, 2009 with 31 in attendance.<br />

There were 18 members and 15 guests in attendance. Four of the guests requested<br />

membership.<br />

Rosters were circulated, and copies of Draft 6d were handed out.<br />

The current status of the document was discussed and it was noted that the PAR<br />

expires in December 2009.<br />

Draft 6d was then reviewed.<br />

Section 5, Cabinet Construction, was discussed. It was mentioned that it may be<br />

difficult to meet the 5 mils thickness with powder coating, and the group decided to<br />

check into what would be a reasonable minimum thickness. Also, it was pointed out<br />

that the Standard may need to indicate what type of stainless steel should be provided<br />

when the cabinet is stainless. Also, someone asked if a plastic box could be an option.<br />

Next, someone pointed out that the side of the cabinet could use other types of device<br />

mounting than a raised panel.<br />

In Section 5.3, a question was raised concerning exposed terminals. The 120 volts was<br />

questioned, and several reference standards were brought up, including NFPA 70E and<br />

<strong>IEEE</strong> 1584. The voltage limit and whether the section should apply to the entire cabinet<br />

or just the swing panel will be examined further.<br />

The word “sturdy” in Section 5.4 was discussed. In Section 5.6, the conduit plate was<br />

discussed, and the group felt that mild steel should be an option. In further discussion,<br />

the group agreed that the plate should be made of the same material as the control box.<br />

Rain shedding was discussed in Section 5.7. Some members expressed concern about<br />

the requirement for options that may simply add cost, and not value.<br />

Next, Section 5.11 on grounding was discussed. A member stated that there cannot be<br />

paint between the ground cable and the ground, and that this needs to be stated in the<br />

Standard. Also the size of the bus was discussed, as well as the use of braided cable<br />

over a solid conductor.<br />

In Section 5.12, a concern was raised over making the light and GFI outlet standard due<br />

to cost. Also, the type of light should be optional.<br />

Further discussion centered around the wiring in Section 5.13. It was agreed that the<br />

color of the control wire did not matter, as long as the grounding wire is green. SIS wire<br />

was discussed, as well as a few other wire types, as well as minimum wire sizes.<br />

In Section 5.14, time delay relays were discussed, and it was agreed that the word<br />

“adjustable” would be stricken. Also, it was agreed that the time delay relay should<br />

work even if it is de-energized. In Section 5.15, “molded case” was stricken in the<br />

description of the contactors.<br />

In Section 6, it was agreed that a team should be assigned to the numbering and<br />

labeling schemes.<br />

In Section 7, 125 Vac should be 120 Vac, and 120 Vdc should be 125 Vdc.<br />

Before the meeting was adjourned, several teams were formed to work on specific<br />

items in the Standard:<br />

Grounding: Gary Hoffman, David Wallach, and Jean-Philippe Gagnon<br />

Wiring: Saurabh Ghosh, Catherine Hurley, and Phil Swan<br />

Cabinet Construction: Donald Ayers, William Darovny, and James Fairris<br />

The meeting was adjourned at 12:15 pm.<br />

8.9.1.4 WORKING GROUP FOR DEVELOPMENT OF PC57.131, STANDARD<br />

REQUIREMENTS FOR TAP CHANGERS - William Henning, Chairman<br />

The Working Group on Tap Changer Performance met on Monday, April 20, 2009 at<br />

1:45 pm with 14 members and 27 guests present.<br />

The working group chairman asked if anyone in the room had information on patents<br />

that may be essential for the implementation of C57.131, Standard Requirements for<br />

Tap Changers. It was noted that no one present at the meeting expressed knowledge of<br />

essential patents.<br />

The working group chairman asked if there were any additions or corrections to the<br />

meeting minutes of October 6, 2008. There being no corrections, the minutes were<br />

approved.<br />

The working group chairman gave a report on the status of PC57.131/D1.4. Draft 1.3<br />

had been submitted for editorial review. The review indicated 23 changes required to<br />

the document to meet the style manual. Draft 1.4 incorporates those changes. An<br />

invitation to ballot was initiated, to close on May 16. The chairman will meet with Matt<br />

Ceglia regarding the next steps.<br />

Under unfinished business, the working group debated a motion, made by Phil<br />

Hopkinson, to insert a clause in 7.2 of C57.131, which would require and define a<br />

functional life test for de-energized tap changers. The motion was seconded by Tom<br />

Lundquist. Five members, who could not attend the meeting, submitted written<br />

comments ahead of time. These were read by the chairman.<br />

Out of the ensuing debate emerged a new proposal, summarized in three points:<br />

Page 94 of 160

1. The Task Force on Functional Life Test for De-energized Tap Changers will go<br />

back and prepare written text, specifying the requirements and test procedure in<br />

more detail, to be evaluated by the working group for inclusion in the next<br />

revision of C57.131.<br />

2. The Working Group on Tap Changer Performance will proceed with its <strong>IEEE</strong><br />

ballot, already in the pre-ballot stage, of Draft 1.4, which does not contain the<br />

Functional Life Test for De-energized Tap Changers.<br />

3. Negative votes because the Functional Life Test is not included may arise. The<br />

attempt to resolve any negative votes on the account will be to offer that the<br />

proposal will be included in the next revision of C57.131.<br />

The original motion was withdrawn, and a new motion, consisting of the above three<br />

points, was made and seconded. The results of a ballot among all present was:<br />

INFORMAL BALLOT RESULTS<br />

A. 13 for<br />

B. 10 against<br />

C. 7 abstain<br />

D. 11 not voting<br />

The motion was adopted by a margin of three votes. The Task Force on Functional Life<br />

Tests for De-energized Tap Changers and the Working Group on Tap Changer<br />

Performance, C57.131, will proceed as outlined above.<br />

That concluded unfinished business. There being no new business, the meeting was<br />

adjourned at 3:02 pm.<br />

8.9.1.5 WORKING GROUP FOR DEVELOPMENT OF PC57.150, GUIDE FOR THE<br />

8.9.1.7 WORKING GROUP FOR REVISION OF C57.135, GUIDE FOR THE<br />

APPLICATION, SPECIFICATION AND TESTING OF PHASE-SHIFTING<br />

TRANSFORMERS – Jin Sim, Chairman<br />

The WG for revision of the Phase Shifting Transformer Guide, C57.135, met Tuesday at<br />

11:00 with 14 members and 7 guests. The <strong>IEEE</strong> Patent Policy was discussed with no<br />

conflicts noted. The minutes from the fall ’08 meeting in Porto were approved with no<br />

changes.<br />

The Chair opened the meeting with a discussion of the plans and schedule for this<br />

Guide. This meeting was the last regular meeting to introduce any new topics or<br />

materials. All changes up to and including the ones in this meeting will be incorporated<br />

into a Draft 4 which will be posted on the <strong>Transformers</strong> <strong>Committee</strong> website then<br />

submitted to the Standards Association for <strong>IEEE</strong> review and balloting.<br />

The majority of the meeting involved review of the changes made in Draft 3 and<br />

suggested changes for the next revision received from Deitrich Bonmann and<br />

distributed to the WG a few weeks before the meeting. The final resolutions of those<br />

suggested changes are as follows:<br />

• Section 4.5.1: The sentence on page 19 …”The user’s electric power system<br />

requirements and the manufacturer’s preference generally determine the design.”<br />

Was changed to…” The user’s electric power system requirements and the<br />

user’s or manufacturer’s preference generally determine the design.”<br />

• Section 4.5.1: The list of factors in determining the type of PST to use for an<br />

application was divided into two sections with four subsections and a new first<br />

section was added as follows:<br />

<strong>IEEE</strong>/<strong>PES</strong> <strong>Transformers</strong> <strong>Committee</strong><br />

Spring, 2009 Meeting Minutes - Unapproved<br />

Technical restraints limiting the choice of PST solutions<br />

Performance factors<br />

1. The power rating and phase-shift angle requirements<br />

2. The voltage and voltage regulation<br />

3. The connected system’s short-circuit capability<br />

Design factors<br />

1. Type of construction (core form or shell form)<br />

2. Layer or disc winding design<br />

3. Shipping limitations<br />

4. Load tap changer (LTC) performance specification<br />

Miami, Florida<br />

April 19-23, 2009<br />

Page 98 of 160

• Section 4.5.1: The existing list of factors in determining the type of PST to use,<br />

from Draft 3, was kept as the second section, with the following section header<br />

added:<br />

Items for the comparison of risks and total costs of different PST solutions<br />

• Section 4.5.2: The following text had been deleted from Draft 3, but was reinstalled<br />

in this section:<br />

Voltage per tap and current are determined by the phase angle<br />

requirement and rating of the PST and cannot be adjusted to obtain<br />

optimum switching conditions. If one of these parameters exceeds its limit,<br />

the solution would not be possible although the required switching<br />

capability may still be given.<br />

• Section 4.5.2: The following text was added to the beginning of the second<br />

paragraph after discussions of possible alternate designs:<br />

For the configurations shown for single core designs in this guide,<br />

• Section 4.7.2: The following was added to the end of this section:<br />

When a tap change is performed for two PSTs connected in parallel, they<br />

may operate on different taps for the short time until both tap changers<br />

have completed their motion. The voltage difference of one tap will drive a<br />

circulating current through the two PSTs, which is limited by the sum of<br />

the PSTs impedances only. The tap changers have to have sufficient<br />

margin for switching the load current superposed with the circulating<br />

current. Single core PSTs as described in 4.5.2 cannot be operated in<br />

parallel with other single core PSTs or some duel core PSTs, unless<br />

reactors are inserted to limit the circulating current. In general, paralleling<br />

PSTs without considerations at time of design could lead to significant<br />

circulating currents and limitation on the LTC operations.<br />

• Section 5.4.1: A brief definition of “buried CT’s” was added as “all CT’s other<br />

than bushing CT’s” and the following sentence was added to this section:<br />

All buried CTs should be equipped with compensating windings in order to<br />

avoid false signals due to magnetic stray fields caused by the windings or<br />

internal connections during external faults or during inrush.<br />

• Section 7.1: This section covers throat connections and the need for the throat to<br />

be designed to withstand vacuum processing. It was expanded with the following<br />

text added to the existing section to clarify the requirements:<br />

…such that oil filling of the tanks can be carried out independently (i.e.<br />

pulling full vacuum on one tank while the throat and other tank are filled<br />

with oil).<br />

• A new Section 12.2.3 was inserted into Section 12, the Bid Document Check List<br />

as follows:<br />

12.2.3 Parallel operation of two or more PST’s<br />

The meeting adjourned at 12:15.<br />

The buyer should state in the bid documents if they intend to<br />

operate the PST in series or in parallel with any existing or sister<br />

units.<br />

8.9.1.8 WORKING GROUP FOR REVISION OF C57.12.10, STANDARD<br />

REQUIREMENTS FOR LIQUID IMMERSED POWER TRANSFORMERS -<br />

Javier Arteaga, Chairman<br />

1. Javier Arteaga opened the meeting announcing the PAR has been extended until<br />

December 31, 2009 and the ballot group has been formed. Javier then<br />

announced that he was resigning as Chairman of the Working Group.<br />

2. Tom Lundquist solicited volunteers for Chairman and Gary Hoffman volunteered<br />

to be Chairman, Saurabh Ghosh volunteered to be Vice Chair and Jim Graham<br />

volunteered to be Secretary.<br />

8.9.1.9 WORKING GROUP FOR THE REVISION OF <strong>IEEE</strong> STD 638-1992, <strong>IEEE</strong><br />

STANDARD FOR QUALIFICATION OF CLASS 1E TRANSFORMERS FOR<br />

NUCLEAR POWER GENERATING STATIONS – Craig Swinderman,<br />

Chairman<br />

Date: Tuesday, April 21, 2009 – 1:45 pm to 3:00 pm.<br />

Attendees: 2 members + 6 guests, one guest requested membership.<br />

The meeting began at 1:45 pm.<br />

The meeting minutes from October 2008 meeting were approved.<br />

The <strong>IEEE</strong> patent policy slides were shown. An opportunity was provided for the<br />

attendees to identify or disclose patents that may be essential for the use of the<br />

standard. No responses were given by the attendees of the meeting.<br />

Topics discussed:<br />

The latest version of the P638 document is now Draft #3. This latest draft was reviewed<br />

during the meeting. This draft #3 of the document will be posted to the transformers<br />

committee website shortly. The majority of the document is nearly complete, but a few<br />

remaining items need to be addressed.<br />

During the review of the information contained in the updated Annex A of the draft<br />

document that describe the thermal aging procedures and calculations, it has been<br />

discovered that some of the figures and graphs included in the annex, which are<br />

updated figures pulled from another referenced standard C57.96-1999, are actually<br />

incorrect. One figure is the curve on relative life expectancy as a function of hottest<br />

spot temperature, in which case the curves are plotted incorrectly. Additionally, during<br />

the meeting, one of the members pointed out that the equations shown on the additional<br />

figures containing the logarithmic graphs of “life expectancy curve – base 10”, have<br />

incorrect coefficients in the formulas, as it appears that the decimal points might be in<br />

the wrong place. A working group member has volunteered to help correct these<br />

figures in our document. We will try and obtain the original formulas for the curves and<br />

have the curves re-plotted correctly. This work will be completed prior to this June.<br />

During our last working group meeting in October 2008, a new section was added to the<br />

document to address concerns raised during the re-affirmation ballot regarding<br />

transformers subjected to non-sinusoidal loads, referencing C57.110. We again<br />

reviewed this new section during the working group meeting, and some members<br />

questioned whether this really applied to class 1E applications, as this standard applies<br />

to a very specific transformer application, and these applications may not necessarily be<br />

subject to non-sinusoidal loads in service. We are now preparing a survey to send to<br />

additional users for more information on the validity of the non-sinusoidal load concerns<br />

for this particular application. We hope to have the results of this survey back by this<br />

June.<br />

On and editorial note, there are some standards in the normative reference list of the<br />

existing document that are not referenced in the body of the document. These<br />

references will be moved to the bibliography at the end of the document.<br />

The current planned schedule for the working group is to have draft #4 of the document<br />

completed by this June 2009. We will then send the document out for a straw vote in<br />

early 2009, and then submit the document for the Mandatory Editorial Review and hope<br />

to start balloting around the time of our next meeting in October 2009.<br />

The meeting adjourned at 3:00 pm.<br />

8.9.1.10 WORKING GROUP FOR DEVELOPMENT OF PC57.153, GUIDE FOR<br />

PARALLELING TRANSFOREMRS – Tom Jauch, Chairman<br />

Attendance included: 14 members, 31 guests with 5 requesting membership<br />

• Minutes of the previous meeting were approved – no patent issues were found<br />

• The need for better participation by working group members was discussed. To<br />

improve communication within the working group and to expedite the<br />

development of the guide, a commitment was made by the officers to circulate<br />

the guide every 4-6 weeks.<br />

• The volunteers from previous meetings were presented to remind everyone of<br />

the commitments they made.<br />

• Volunteer changes and additions received during the meeting:<br />

o Power Factor Method – Until the determination of a proposed new<br />

“combination” paralleling method by Dr. Karsten Viereck – Reinhausen,<br />

Jim Harlow – Harlow Engineering to postpone his work on the Power<br />

Factor Method.<br />

o Master Follower with odd/even cam switches – Daniel Blaydon –<br />

Baltimore Gas & Electric – will look through his company archives for<br />

Westinghouse and GE manuals that discuss this method.<br />

• Proposal was made to add a “combination” paralleling method. The working<br />

group will discuss this proposal at the next meeting. Comments included a<br />

question for the necessity of the “new” method. It was suggested that it was a<br />

subset of the Power Factor Method and that creating a separate method for it<br />

was not required.<br />

• Benefits and limitations of each method should be addressed when discussing<br />

the paralleling method.<br />

• The guide should address the location of the LTC’s.<br />

• Sanjib Som – Virginia Transformer led the discussion on a list of questions and<br />

concerns that manufacturers have when transformers are being paralleled.<br />

There was debate on which of these items should be covered by the guide.<br />

Presently the PAR for the working group focuses on control methods for<br />

paralleling.<br />

• An invitation was made for everyone to attend transformer paralleling tutorial on<br />

Tuesday.<br />

• Meeting was adjourned at 4:30pm.<br />

8.9.1.11 TASK FORCE FOR TRANSFORMER TANK RUPTURE AND MITIGATION –<br />

Peter Zhao, Chairman<br />

Meeting of the Task Force for Tank Rupture & Mitigation convened Tuesday morning at<br />

8:00am. Chairman Peter Zhao presided.<br />

Knowledge of patent concerns was requested, with none cited.<br />

Attendance was 44 (14 members, 30 guests).<br />

The status of the White Paper that this task force has been working on was reported by<br />

Terry Lee. The White Paper, which was originally submitted for approval in early<br />

February, 2008, was well received by reviewers - but required various revisions before<br />

approval. Approval was received March 2009, with expectation of inclusion in next<br />

publication of <strong>IEEE</strong> Transactions – Power Delivery.<br />

The chairman announced that the paper is to be presented at the July 26, 2009 <strong>IEEE</strong><br />

<strong>PES</strong> general meeting in Calgary, and requested volunteers from among the writers to<br />

do the presentation. With no immediate response to the request, the chairman<br />

requested that any interested party contact him after the meeting.<br />

The chairman confirmed that with the publication of the white paper, the work of the<br />

Task Force is essentially complete, and called for discussion of the question of whether<br />

a PAR should be issued for development of an Application Guide. As a result of the<br />

discussion, the question was tabled until the fall ’09 meeting, to allow members to<br />

become familiar with the final version of the white paper – which will be issued to<br />

members only.<br />

The meeting proceeded with discussion of scope of an Application Guide, so that work<br />

can proceed under the assumption that a PAR is to be presented. Areas of work for<br />

which volunteers are needed were discussed with following assignments confirmed:<br />

1. General introduction: Terry Lee, Devki N Sharma, Patrick McShane, Harold<br />

Moore, and Peter Zhao<br />

2. Transformer tank construction: Bill Darovny, Mike Lau, Dan Perco, Raj Ahuja.<br />

3. Pressure Relief Device: Josh Hertz, Guillaume Perigaud.<br />

4. User Specifications: Dennis Marlowe, Dan Perco, Jim Zhang, Bill Darovny,<br />

Patrick McShane, Harold Moore, and Peter Zhao<br />

5. Acceptance Evaluation: Dan Perco, Arnold Carlos.<br />

Underlined names are leaders of each team.<br />

The chairman informed volunteers that work of each team is due to him by the end of<br />

the first week of September (2009), in order to allow review at the fall ’09 meeting.<br />

Craig Swinderman presented an informative summary of “Industry Standards and<br />

Recommendations on Transformer Tanks” including excerpts from IEC 60076-1 (tank<br />

testing) and CIGRE Brochure 156 (Guide for Specifications for <strong>Transformers</strong>).<br />

The meeting was adjourned at 9:15am.<br />

8.9.1.12 TASK FORCE FOR EVALUATING THE NEEDS OF TRANSFORMERS USED<br />

Mr. C. J. Kalra served as the shoe-in secretary for this meeting. The meeting started<br />

with introduction of participants.<br />

The <strong>IEEE</strong> Patent Disclosure issue was brought forth to the attention of all attendees.<br />

In the absence of any the previously circulated Task Force Assignment was illustrated<br />

to the participants. Attention was drawn also to the <strong>IEEE</strong> Std 929-2000 shared by<br />

Amitav Mukerji of ABB, Cary, NC. At the suggestion of several participants including:<br />

Tom Lundquist, Bill Chu, Sanjib Som, Mathieu Sauzay, Donald Ayers, Charles Williams;<br />

issues regarding the direction in which the TF should proceed were discussed. After a<br />

lengthy discussion it was decided to start focusing on the real issues faced by DPV –<br />

Grid <strong>Transformers</strong> related to:<br />

1) Islanding<br />

2) Voltage Flicker<br />

3) Voltage Operating range<br />

4) Frequency variation<br />

5) Waveform Distortion<br />

6) Power factor variation<br />

7) Safety and Protection functions<br />

Related Standards besides the above like <strong>IEEE</strong> 519 and others were brought to the<br />

notice of the participants. It was decided to create a matrix which shows the information<br />

already available in existing <strong>IEEE</strong> standards that address the above (1) – (8) topics and<br />

assess the existing gap in this information and seek help from participants and<br />

interested experts to share the load in contributing to these tasks and important chores<br />

specifically: Bill Chu, Sanjib Som, Mathieu Sauzay, Donald Ayers, and Charles<br />

Williams. Several of the above mentioned participants have agreed to help out in<br />

addressing these issues and formulating the future direction the TF should take going<br />

forward in satisfying the charge placed in front of the TF by the SC – Power<br />

<strong>Transformers</strong> in Oporto, Portugal in October of 2008. The Chair will issue future<br />

notifications to these members/guests in preparation of the next meeting in Chicago.<br />

There being no further business, the meeting was adjourned at 9:15 am.<br />

8.11. “AUDIBLE SOUND AND VIBRATIONS” SC - Chairman: Jeewan Puri<br />

8.11.1. Introduction and Chairman’s Remarks<br />

The Sub <strong>Committee</strong> met on Wednesday, April 22, 2009 with 13 members and 16 guests<br />

present. After introductions and chairman’s remarks, the participants discussed the<br />

following issues.<br />

8.11.2. WG Report<br />

8.11.2.1. PC57.151 - Jeewan Puri<br />

It was pointed out that the PAR C57.151 for writing sound level measurement guide will<br />

expire in Dec. 2009. J. Puri will apply for extension of this par.<br />

The WG started the review of the proposals made by Ramsis Girgis regarding the<br />

revision of Section 13 of <strong>IEEE</strong> Standard C57.12.90 and C57.12.91. Based on the work<br />

done by him and his colleagues, he proposed the following:<br />

1. The presently used sound pressure measurements are over stated due to errors<br />

introduced by:<br />

• Near Field effects (0 to 2 dB)<br />

• Ambient Noise (0 to 2 dB)<br />

• Wall Reflections (1 – 2.5dB)<br />

It was proposed that correction for wall reflections should also be allowed.<br />

2. Ramsis reviewed the extensive work that he and his colleagues have done in<br />

measuring sound intensity using discrete frequency measurement technique.<br />

This method improves the accuracy of sound intensity measurements as<br />

compared to commonly used dB A measurements. This method is particularly<br />

useful when making measurements on transformers with low sound level<br />

guarantees. He pointed out that for making sound intensity measurements with<br />

the acceptable accuracy the following sound pressure(Lp) and sound intensity<br />

(Li) level difference limits should be used:<br />

• (Lp-Li) < 5dB - for discrete frequency measurements<br />

• (Lp-Li) < 6dB - for dB A measurements<br />

Based on the measurement data presented, it was agreed that these limits<br />

should be accepted.<br />

3. It was agreed that it was agreed that a note should be added in this section<br />

pointing out the enhanced accuracy of far field dBA sound level calculations<br />

using discrete frequency sound intensity measurements.<br />

Page 109 of 160

4. It was agreed that the discussion on modifications to Section 13 proposed by<br />

Ramsis and his colleagues will continue in our next meeting.<br />

8.11.2.2. Revision of C57.12.90 Section 13 – Ramsis Girgis<br />

Ramsis reviewed the work presented in the WG with the SC.<br />

It was pointed out the sound emitted from the transformer covers could be a significant<br />

influence for people living in high-rise buildings. Sound emission from the covers of<br />

transformers with gas cushions versus transformers provided with conservator type oil<br />

preservation systems was discussed.<br />

It was also pointed out that the reflection coefficients for different frequency noise levels<br />

are not the same. This could be a source of error in computing sound level correction<br />

for sound level measurements.<br />

It was agreed that these issues produce only secondary influences on sound level<br />

measurements and should be discussed in the sound level measurement guide.<br />

8.11.2.3. Next draft of Sound Abatement Guide C57.136 – Allen Darwin<br />

Allen reported that this guide will be due for revision in 2010. This work will be done only<br />

after Section 13 of the test standards have been modified.<br />

8.11.3. There being no new business, the meeting adjourned at 9:15 am.<br />

8.12.4.2 TF - Revision of C57.19.100 – Tommy Spitzer, Chair<br />

The meeting was called to order at 3:15 on April 21, 2009 with 15 members and 13 guests.<br />

There were no patent disclosures. The Spring 2008 minutes were approved. There was no<br />

meeting in Porto. Jesse Patton replaced Charlie Caruso who has retired.<br />

TF completed review of Draft 2, and a new draft will be created from the comments of Draft 2.<br />

The Chair plans to have the draft completed to begin balloting by end of the year. The PAR is<br />

active until 12/31/2010.<br />

The meeting was adjourned ad 4:30.<br />

8.12.4.3 TF – GSU Bushings – Catherine Hurley<br />

Minutes: Meeting of the Task Force for Generator Step-Up (GSU) Bushing Standardization<br />

April 21, 2009 1:45 pm<br />

1. Attendance: There were 30 people in attendance, as follows: 15 Members; 1 Requesting<br />

Membership, 13 Guests and 1 did not mark any designation. Introductions were made<br />

by everyone.<br />

2. Agenda: An Agenda was presented by the Chair of the Task Force.<br />

3. Minutes: The Minutes of the last meeting in Porto, Portugal were presented and<br />

approved.<br />

4. Comments on Title and Scope: The Chair sent a copy of the Title and Purpose via email<br />

to participants of the Task Force, and she received comments. The TF proceeded to<br />

discuss the comments, as follows:<br />

Title:<br />

a. There was considerable discussion of the Title, and whether it should include a<br />

reference to Outdoor and Apparatus It was decided that “Outdoor” would be<br />

removed but that there was no agreement on the word Apparatus. Some<br />

suggestions were to add Power before this or to replace with <strong>Transformers</strong> and<br />

Reactors. This will be resolved by emails.<br />

b. The <strong>IEEE</strong> Administration will have to review and approve the Title.<br />

Purpose:<br />

c. There was considerable discussion about the purpose of the Standard. It<br />

was suggested to keep it the same as that in C57.19.00 but a review of that<br />

Standard showed there was no clause labeled purpose in that document.<br />

Thus it may not be required but is desirable to show the need for this<br />

Standard which is not in any other Standard.<br />

5. Table 1 was discussed in general terms to determine if the 110 kV BIL should be kept<br />

and after discussion it is still included as there are many 13.8 kV bushings out there.<br />

6. PAR: The Chair’s intent is to draft the PAR and send it out for comment before it is<br />

formally submitted. The draft version of the PAR will be sent via email to participants of<br />

this meeting and will be approved via emails. Comments should be sent back to<br />

cahurley@aep.com .<br />

7. Adjournment: The meeting was formally adjourned.<br />

8.12.4.4 C57.19.03 – DC Bushing Standard – Les Recksiedler, Chair<br />

The WG met on April 21, 2009. Eleven (11) members and twenty-one (21) guests attended the<br />

meeting. Four (4) guests requested membership. The meeting was chaired by Mr. Les<br />

Recksiedler and the Vice-Chair was Pierre Riffon.<br />

Minutes of Porto meeting were approved as written.<br />

The <strong>IEEE</strong> patent disclosure requirement policy was discussed. None of the members and<br />

guests present during the meeting were aware of any patents related to the work of the WG.<br />

The first subject on the agenda was the possibility to establish a joint <strong>IEEE</strong>/IEC Working Group /<br />

Maintenance Team in order to get a dual-logo standard on DC bushings since the contents of<br />

actual <strong>IEEE</strong> and IEC standards are quite similar. After having discussed several practical<br />

operational matters with <strong>IEEE</strong> officers, the WG voted to go for a joint WG/MT with IEC. None of<br />

the WG members did oppose to this proposal. The IEC format and template will be used. A<br />

modified PAR needs to be submitted to <strong>IEEE</strong>. Such joint WG/MT still needs the approval of the<br />

Bushings Sub<strong>Committee</strong> and the approval of a New Work Item Proposal by National<br />

<strong>Committee</strong>s participating to the work of IEC SC36A.<br />

The remaining part of the meeting was dedicated to the review of proposals made by Pierre<br />

Riffon during Porto meeting. These proposals have been implemented into D1 of the revision of<br />

C57.19.03. Most of the proposals were deemed acceptable to the WG membership. One point<br />

which needs to be modified is related to the procedure to be used during temperature rise test<br />

for simulating high ambient air temperature of HVDC valve halls. Reiner Krump will make a<br />

counterproposal prior to next meeting.<br />

A new Annex proposed by Ulf Radbrandt related to DC bushings used in VSC HVDC<br />

converters has been reviewed. This Annex is based on similar Annexes used in C57.129 on<br />

HVDC Converter <strong>Transformers</strong> and in the upcoming revision of <strong>IEEE</strong> Std. 1277 on HVDC<br />

smoothing reactors. A revised version will be produced and will give more details related to<br />

bushing design in relation with fast switching voltage transients produced by such DC<br />

converters.<br />

The meeting adjourned at 10:45 am on April 21, 2009.<br />

IIEC Meetings<br />

The IEC committees TC36 “Insulators” including SC36A “Bushings” meet during the IEC<br />

General Session in Sao Paulo, Brazil during the week of November 17 th 2008. Fourteen<br />

countries were represented with the main discussion being;<br />

IEC60137 “Insulated Bushings for Alternating Voltages above 1000V”<br />

Edition 6 was published in July 2008 following a majority positive vote by National <strong>Committee</strong>s.<br />

The Japanese delegate pointed out the lack of technical justification for the recent revision of<br />

testing of transformer bushings. Japan requested that work start immediately to gather<br />

information on bushing failures in transformer test. While it was agreed to request Cigré A2 –<br />

<strong>Transformers</strong> to investigate failure rates the maintenance date for IEC60137 was set at 2011.<br />

During future revision the working group should address inconsistencies in the test method for<br />

temperature rise of external connections – this inconsistency also exists in <strong>IEEE</strong> C57.19.00.<br />

This work by SC36A MT5 is now closed.<br />

IEC62199 “Bushings for DC Application”<br />

It was proposed that SC36A MT5 take over the review of this document.<br />

This standard is the IEC equivalent of <strong>IEEE</strong> C57.19.03 currently under review. It was agreed<br />

that this document is a suitable candidate for dual numbering by IEC/<strong>IEEE</strong>. There has been<br />

correspondence between the Officers of IEC and <strong>IEEE</strong> on this subject and it is referred to the<br />

<strong>IEEE</strong> Working Group meeting in Miami.<br />

Other Work –<br />

It was agreed to liaise with IEC TC10 Insulating Fluids on “Condition assessment of insulating<br />

liquids in electrical equipment”. In this would TC10 would be responsible for test techniques and<br />

SC36A would be responsible for condition assessment of bushings.<br />

The maintenance result date for IEC61464 “Guide for the interpretation of DGA in bushings”<br />

was extended to 2013.<br />

<strong>IEEE</strong> High Current Bushing TF – it was agreed that IEC had no interest in this work.<br />

UHV Products – A joint IEC / Cigré working group (JICCG) has been set up with the scope of<br />

standardisation of ratings for UHV AC and DC equipment. Bushings are a particular focus of this<br />

group but to date SC36A has not considered any implications on standards.<br />

The next meeting of SC36A is planned for Seattle in October 2010 in conjunction with the IEC<br />

General Meeting.<br />

9.0 - Editor’s Report – Spring 2009 Miami Meeting – Editor - Ed teNyenhuis<br />

Since January 2009, I have officially taken over the responsibility of the Editor position from John<br />

Crouse. John agreed to continue to follow through on any remaining papers that were still in the “Revise<br />

& Resubmit” process from during his time as editor. This is thus a combined report.<br />

Between Oct 5, 2008 and April 19, 2009, a total of 54 new & resubmitted papers in the transformer area<br />

were submitted to <strong>IEEE</strong> Transactions on Power Delivery for possible publication. For the 32 reviews<br />

completed during this period, the recommendations were:<br />

Accept without changes: 7<br />

Revise and Resubmit: 12<br />

Reject: 13<br />

Another 22 papers are under review or are being processed to send out for their initial review.<br />

A summary of the accepted papers is at the end of this report.<br />

I would like to thank all of the reviewers who volunteered for this effort and donated their time, and<br />

would like to encourage everyone associated with <strong>IEEE</strong> <strong>Transformers</strong> <strong>Committee</strong> activities to consider<br />

becoming a Reviewer. The comments and suggestions of the reviewers improve the quality of the papers<br />

that are published and we need the help of all of you to ensure that we continue to have quality papers that<br />

benefit all of us.<br />

I would like to encourage those Reviewers that already have an account on <strong>IEEE</strong> Manuscript Central to<br />

keep their profile information updated and complete the areas for key words and areas of interest. We<br />

need more reviewers and I encourage any of you that have not signed up as reviewers to sign up per the<br />

Page 121 of 160

The Chairman suggested deferring this issue as the voting result is too close and <strong>IEEE</strong> is<br />

already producing a document which could later be adopted as a dual-logo Standard<br />

6.3 <strong>IEEE</strong> Standard C57.15 D8.3 – potential documents for dual-logo Standard<br />

Mr Charles Jacquemart suggested that the US NC could circulate a NP to P-Members to see<br />

if there are enough P-Members supporting this proposal. The work could be done under a<br />

Joint IEC/<strong>IEEE</strong> Working Group according to AC 22, 2008.<br />

By show of hands, the following countries supported this proposal: Brazil, US, Italy and<br />

Nigeria.<br />

6.4 <strong>IEEE</strong> C57.123 as a potential dual-logo Standard according to AC 22, 2008<br />

Mr Karl-Heinz Haeger (DE) recommended not including <strong>IEEE</strong> C57.123 as an IEC/<strong>IEEE</strong><br />

dual-logo Standard. After some discussion there was no support for the inclusion of this <strong>IEEE</strong><br />

Standard as a dual-logo Standard.<br />

It was suggested that the lack of support for the <strong>IEEE</strong> standards was due to protectionism.<br />

Delegates were looking after their own national or company’s interests. Another possibility<br />

is that the delegates recognize that dual logo documents are not very useful. A base<br />

document with a header and footer attached is not a very useful document. Any changes<br />

needed to be acceptable to IEC need to be made to the document before it is offered to IEC.<br />

A better route may be to use a joint working group between IEC and <strong>IEEE</strong>.<br />

6.5 Establishment for Category D liaison with <strong>IEEE</strong><br />

<strong>IEEE</strong> should send a request to IEC to specify which WG they want a category D liaison with,<br />

within IEC/TC 14. Phil Hopkinson agreed to take this message back to <strong>IEEE</strong>. Jin Sim has<br />

been proposed to be a Cat D Liaison to MT5, however the proper paperwork has yet to be<br />

completed.<br />

6.6 Plenary Meeting 2009<br />

The US has been asked to host the 2009 TC14 Plenary meeting. An invitation has been<br />

issued to host the meeting November 19-20, 2009, at/near the NEMA offices in Rosslyn, VA.<br />

Working group and Maintenance Team meetings will be held November 16-18.<br />

This is an excellent opportunity for US members to attend the meeting as an observer, and a<br />

few of the attendees expressed interest.<br />

7.4 IEC 60076-3: Power transformers - Part 3: Insulation levels, dielectric tests and external<br />

clearances in air:<br />

<strong>IEEE</strong>/<strong>PES</strong> <strong>Transformers</strong> <strong>Committee</strong><br />

Spring, 2009 Meeting Minutes - Unapproved<br />

This is a new project, with Mr. Shirasaka (Japan) is the Convenor. Experts are sought for the<br />

MT. Rick Marek and Ramsis Girgis are to be nominated to USNC as experts.<br />

A new scope has been proposed. Comments (approval, additions, etc.) are requested by TC14<br />

by 15 May 2009<br />

Scope for the maintenance of IEC 60076-3 Power transformers –Part 3 Insulation Levels,<br />

Dielectric tests and external clearances in air.<br />

The scope of work for the maintenance team to revise IEC 60076-3 is as follows:<br />

1) Consider the work of the Joint IEC/CICRE working group on UHV and propose dielectric<br />

test levels for transformers with Um > 800kV.<br />

2) Consider means of improving the clarity of the document, for example by splitting the<br />

document into parts relating to specific voltage ranges.<br />

3) Consider whether all the test connections given in the document are still relevant and<br />

practically used.<br />

4) Ensure that phase to phase test levels are adequate for three phase transformers tested<br />

using a single phase test supply.<br />

5) Consider whether a reduction in the number of possible test voltages given in tables is<br />

possible and whether the test level tables relating to ‘North American practice’ need to be<br />

revised following the recent revision of the equivalent <strong>IEEE</strong> document.<br />

6) Consider whether greater compatibility with <strong>IEEE</strong> test methods and levels is possible or<br />

desirable.<br />

7) Consider whether any changes to IEC 60060 are relevant to this document<br />

8) Make any technical and editorial changes required to improve the accuracy and clarity of<br />

the document, or to bring it up to date.<br />

7.5 IEC 60076-10 Ed. 2.0 - Power transformers - Part 10: Determination of sound levels<br />

(Convenor: Dr. C. Ploetner)<br />

This is a new maintenance project, and the Convenor will be Dr. C. Ploetner. Ramsis Girgis<br />

and Jeewan Puri are to be nominated to USNC as experts<br />

Proposed scope revision – comments (approval, additions, etc) are requested by TC14 by<br />

comments: 1 May 2009.<br />

Proposed scope for the establishment of a new maintenance team for the Revision of IEC<br />

60076-10 Power <strong>Transformers</strong> - Determination of Sound Levels<br />

Since edition 1 of IEC 60076-10 in 2001 was published, it was possible, to carry out sound<br />

intensity and additionally or alternatively sound pressure measurements. In between, many<br />

results, based on measurements in test laboratories of transformer manufacturers, are<br />

available. Evaluations demand clarifications in revision work. Among others, following items<br />

should be processed by the maintenance team:<br />

1. When both measurements (sound pressure and sound intensity) are carried out under<br />

similar conditions, a deviation between sound pressure and sound intensity measurement is<br />

detected.<br />

2. It was found, that the mainly historically justified measuring distance of 0.3m and its<br />

application rules cause under certain conditions erroneous measurements.<br />

3. The correction due to the background noise should be improved and be more severe. The<br />

same applies to the correction due to reflexions of the measured values (corrections, caused<br />

by reflexions, should be proven by measurements).<br />

8. OTHER ISSUES<br />

Transformer efficiency may be addressed by TC14 in the future. An excerpt from SMB/3970/R<br />

is provided below<br />

Power transformers IEC/TC14 - Priority 1<br />

SG1 Recommendation 3a:<br />

IEC/TC 14 “Power transformers” to develop a common classification and associated calculation<br />

methods for power transformers with a view to facilitate harmonization of energy labelling<br />

schemes existing at various national and regional levels. It is anticipated that the resulting IEC<br />

publication will be of particular interest for use in industrial distribution systems.<br />

Note 1: Attention is drawn to (among others) CENELC EN 50464-1:2007, which provides a loss<br />

level classification for three-phase oil-immersed distribution transformers 50 Hz, from 50 kVA to<br />

2 500 kVA with highest voltage for equipment not exceeding 36 kV. See item 4 in<br />

SMBSG1/Italy02 for further national standards to be considered in this context.<br />

Note 2: As a first step of harmonisation, a Technical Report or a Technical Specification could be<br />

considered, however, eventually an International Standard seems to be desirable.<br />

approved (SMB/3718B/R SMB/3718C/CC)<br />

SG1 Recommendation 3b:<br />

Furthermore, a guideline document (Technical Report) is required on the choice of the optimal<br />

transformer in a given application.<br />

approved (SMB/3718B/R SMB/3718C/CC)<br />

Standards Report<br />

To: Members of <strong>IEEE</strong> <strong>Transformers</strong> <strong>Committee</strong><br />

From: Bill Bartley, Standards Coordinator<br />

Date: April 1, 2009<br />

Re: Transformer Standards Activity since October, 2008<br />

Executive Summary<br />

This report covers the Standards activity for the six-month period of October 1 2008 to April 1, 2009. The<br />

Transformer <strong>Committee</strong> is responsible for approximately 96 active standards, plus 45 projects for new<br />

standards and revisions. In the last six months, one Revision and two Reaffirmations were approved by<br />

REVCOM. In addition, REVCOM extended four of our standards, due to work in progress. In the last six<br />

months, NESCOM approved one PAR for a new standard, one PAR for a revision /amendment, three PARs<br />

modifications, and three PAR extensions. We have seventeen standards which may expire at the end of<br />

this year; and we have fifteen PAR’s which may expire at the end of this year.<br />

I. Standards News<br />

Procedural Change – <strong>IEEE</strong> requires evidence of consideration<br />

The <strong>IEEE</strong> has implemented a change in the ballot process. Every WG Chair is now required to record a<br />

response in the Comment Resolution spreadsheet for each and every Comment on the Ballot. Any<br />

comments received during the final round of ballot must have a response added in the system.<br />

This does not necessarily require a recirculation, simply a response. This response is required to<br />

satisfy the evidence of consideration requirement.<br />

In addition, if there are negative comments received during that final ballot, there are additional<br />

steps required. If your working group has declared these comments as "Out of Scope" or "Pile-<br />

On Comments to a previously submitted comment in myBallot" an email indicating this<br />

declaration must be sent to the balloter. This email must contain no disclaimer language<br />

(typically found at the bottom of corporate emails) and this email shall be included in the<br />

RevCom submittal package.<br />
