HIGH POWER LABORATORYHigh PowerLaboratory (HPL):ready for an ultra-highpower futureIn November 2012, DNV KEMA announced a 70 million Euro investment in itsHigh Power Laboratory (HPL) in Arnhem, the Netherlands. This investment,which includes two new short-circuit generators, will create the world’sfirst laboratory able to test technologies for super grid componentsoperating at 800 kV and above. The new facilities will also be able tohandle up to 30% more testing activity for conventional high-voltagecomponents.Article on page 4HighLight | February 2013 | 3

HIGH POWER LABORATORYHigh PowerLaboratory (HPL):ready for an ultra-highpower future(continued)Testing and certification have always beenimportant elements in ensuring the safetyand reliability of electricity transmissionand distribution (T&D) networks. But thedynamics of today’s electricity marketsmake them all the more essential.Global demand is rising rapidly, whilecutting CO 2emissions remains anenvironmental priority. According to theInternational Energy Agency’s WorldEnergy Outlook (WEO) 2012, globaldemand for electricity will grow more than70% to almost 32,000 TWh by 2035. Theincrease comes overwhelmingly from non-OECD countries, with over half from Chinaand India aloneGrowing demand for testingThis means a large amount ofnew transmission and distributioninfrastructure will have to come online andexisting capacity will need to be upgraded.Utilities and component manufacturersface considerable pressure to fulfill thesedemands rapidly. R&D cycles are becomingever shorter. However speed cannot comeat the expense of reliability and safety.Major outages are economically, technicallyand socially damaging, as this year’smassive grid failure in India demonstrated.Indeed, the huge impact of outages isleading many countries to implementever more stringent regulations.Moreover utilities often face significantfinancial and judicial penalties if theyare held responsible. In these situations,utilities can use evidence of testing andcertification as a way to prove that they actwith due diligence in selecting equipmentand technologies. And as governmentshurry to extend infrastructure, nationaland international tender requests nowcommonly require products tested andcertified by independent laboratories.So, while testing may not be mandatoryby law, it is increasingly normal practice.Furthermore, the pressure for certificationis likely to increase. For instance, newtypes of investor such as pension fundsare entering the electricity infrastructuresector. These investors do not havetechnical expertise: for them, certificationis a way to assess the safety and viability ofinvestment opportunities.Extreme future-proofedHowever, the enormous demand forelectricity is not just driving expansionof existing grids; it is also leading to thecreation of vast, ultra-high-voltage supergrids. These trans-national or transcontinentalnetworks will facilitate transmissionof high volumes of electricity overvast distances – often integrating renewableenergy with conventional sources.4 | HighLight | February 2013

IN BRIEFTesting of kWh meters with a (pre) payment systemFrequently, kWh meters are equipped with a (pre) payment system. Think of coins,cards or codes to be inserted. Payment meters are used in situations where the supplierof electrical energy wants to be sure about the payment Important for the correctfunctioning of a payment system is the build-in switch in the kWh meter.The standard IEC 620055-31 is applicablefor energy meters with a payment system.DNV KEMA is now able to perform all teststo certify kWh meters with payment systemsaccording to IEC 62055-31.Payment systems are also of interest for thesmart meters. Smart meters are designed tocontrol the use of energy and can also beused as a payment meter. For this purposesmart meters are equipped with a loadswitch to connect or disconnect the powersupply of a client. Purchasers of smartmeters are increasingly demanding kWhmeters be type tested as a whole, the loadswitch included.DNV KEMA offers, besides the metrologypart of the smart meter, different servicesaccording to IEC 62055-31:n Test of a smart meter load switchaccording to annex C of the standardn IEC 62055-31 as an additional serviceon a type test according to IEC 62052-11and corresponding standardsn Complete type test of a payment meterIf the test is completed successfullyaccording to the standard, a Report withresults and a Certificate will be issued.EventsNew IEC standard for current transformersMiddle East Electricity17-19 February 2013Dubai, UAERecently, the IEC standards for currenttransformers have been replaced by anew edition.The former IEC 60044-1 Ed. 1 (1996)including its Amendments andIEC 60044-6 Ed. 1 (1992) related toprotective current transformers fortransient performance, have now beenreplaced by IEC 61869-2 Ed. 1 (2012-09).This new IEC standard for currenttransformers is part of the IEC 61869series, where each part is applicable to adifferent type of instrument transformersuch as current transformers, inductivevoltage transformers, capacitive voltagetransformers, etc.IEC 61869-1 Ed. 1 (2007) describes thegeneral requirements for instrumenttransformers and is therefore to be usedin conjunction with the specific partwhich applies to the type of instrumenttransformer to be tested.Besides the two standards mentionedabove, IEC 61869-3 Ed. 1 and IEC 61869-5 Ed. 1 for respectively inductive andcapacitive voltage transformers havealready been published in July 2011.6 | HighLight | February 2013

TESTING ACTIVITIESABBDNV KEMA High Power Laboratory in Arnhem and ABB,a global leader in power and automation technologies,successfully performed a composite error (100 kA) andinstantaneous error (63 kA (165 kA peak) C-150ms-O-300ms-C-150ms-O) measurement on an optical currenttransformer with digital IEC 61850-9-2 sampled valuesoutput. For the first time a non conventional opticalinstrument transformer with sensitive electronics wastested in the DNV KEMA High Power Laboratory. Becker MiningRecently, Becker tested underground mining electricalequipment as per the IEEE Std C37.20.7-2007 for internalarcing faults. The testing took place at DNV KEMA-Powertest in Chalfont, PA, USA. There are over 600underground mines in America with thousands ofelectrical enclosures that are freely accessible by anyoneworking in the mines. Becker’s purpose in developing arcresistant equipment is to keep miners safe, protect themines’ assets and maximize production. BOS ElektroDNV KEMA Calibration & Metering (C&M) has beena reliable partner for BOS Elektro bv since 1993 andconducts on-site calibrations on their stationary safetytesters. The company manufactures equipment fortemporary power supply and related products, suchas floodlights – wire, cable, connection and maindistribution boxes – heaters, dehumidifiers and switchingequipment. For this company, accurate measurementsare important for quality control. After calibration, themeasurement results are carefully interpreted and againwe were both very satisfied with the results which are allwithin the specifications. Because our DNV KEMA C&MLaboratory is accredited, data is always traceable to anational standard. For Bos Elektro bv this is a requirementbecause the business must meet a quality certificationsuch as ISO, EN, BRL or SEI.
