1. Introduction<br />
This manual is intended to familiarize the new owner of the <strong>800</strong> <strong>Series</strong> <strong>Power</strong> <strong>Analyzer</strong> with the<br />
features and operations of the <strong>Power</strong>Vision analysis software.<br />
The analysis software provides the user with the ability to analyze the data captured by the <strong>800</strong> <strong>Series</strong><br />
<strong>Power</strong> <strong>Analyzer</strong> using an extensive set of analysis tools. Data can be configured into a simple list, or<br />
complex tables and graphs. Data from multiple files may also be compared to determine what has<br />
changed from machine to machine, or how the system has deviated from the baseline readings.<br />
Standard power quality and energy reports can be created to assist in pinpointing problem areas and<br />
opportunities to improve energy management within the facility.<br />
This data can also be exported to a text file or database, and any graphs or tables can be exported as<br />
an image to be placed in excel or word documents.<br />

7) Continue this process until you have selected all of the variables that you wish to graph.<br />
8) Press the OK button to create the graph.<br />
9) Press the Cancel button to leave this screen without creating a graph.<br />
23
6.2.2 Graphing capabilities<br />
The <strong>Power</strong>Vision software tries to create a graph with as many variables as possible because it<br />
assumes that the user wants to perform a side-by-side comparison. If you do not need all the variables<br />
displayed side by side, it is recommended to create separate graphs for the groups of variables that you<br />
want to analyze together. This way you will get better scaling on all graphs.<br />
If the selected variables have the same units of measure, the software will graph them on the same<br />
axis. If they have different units of measure they will be displayed on a split screen with different axes.<br />
If you wish variables with the same unit of measure to be graphed on their own axis, select the<br />
variables with a different unit of measure between them. For example if you are graphing minimum and<br />
maximum voltage for phase 1 and current for phase 1, selecting them in the following order will ensure<br />
that each variable has its own axis: Maximum Voltage Phase 1, Current Phase 1, Minimum Phase<br />
24
If data from more than one file is selected, the software will group the variables by file and create a<br />
separate graph for each file.<br />
There are some variables that may not be graphed with other variables. If multiple variables are<br />
selected, the software will automatically graph these variables in their own graph.<br />
These variables are:<br />
<strong>Power</strong> Factor<br />
Harmonics variables (THD, RMS and wave form)<br />
Disturbances graphs<br />
Events graphs<br />
25
6.2.3 Graphing tools<br />
The <strong>Power</strong>Vision software has a variety of tools to help you interact with the graph and sort through<br />
the data. These tools are located on the graphing toolbar. This toolbar can be enabled or disabled<br />
from either the drop-down configure menu, or by right-clicking the mouse on the graph.<br />
To enable/disable the toolbar:<br />
1) Left-click on the drop-down configure menu, or right click on the graph to bring up the graphing<br />
menu.<br />
2) A check mark next to Toolbar (See Toolbar in the graphing menu) indicates that the graphics<br />
toolbar in enabled. Left-click on Toolbar (See Toolbar in the graphing menu) to remove the<br />
graphing toolbar from the screen.<br />
3) If there is not a checkmark next to Toolbar (See Toolbar in the graphing menu) then the option has<br />
been disabled. Left click on Toolbar (See Toolbar in the graphing menu) to enable the graphics<br />
toolbar.<br />
26
The graphics toolbar has 13 icons to help you interact with the graphs. This section of the manual<br />
gives an overview of each of them. The specific functionality of each is covered in the next section of<br />
this instruction manual.<br />
Save as Icon: With this icon, the user can save the graph displayed on the screen as<br />
a picture file (BMP format).<br />
Clipboard Icon: With this icon, the user can paste the graph displayed on the screen<br />
to the Windows clipboard so it can be pasted into spreadsheet or word documents.<br />
Configure Icon: With this icon, the user can customize the graph.<br />
1 st Period Icon: With this icon, the user can jump to the first period in the graph.<br />
Previous Period Icon: With this icon, the user can move back to the previous period<br />
in the graph.<br />
Next Period Icon: With this icon, the user can move forward to the next period in the<br />
graph.<br />
Last Period Icon: With this icon, the user can jump to the last period in the graph.<br />
Shorter Group Icon: With this icon the user can group the information on the graph<br />
into shorter groups. For example, if the graph is grouped by weeks, you can change<br />
the grouping to days.<br />
Large Group Icon: With this icon the user can group the information on the graph into<br />
shorter groups. For example, if the graph is grouped by hours, you can change the<br />
grouping to days.<br />
Undo Zoom Icon: With this icon, the user can undo all zooms and return the graph to<br />
full screen.<br />
Undo Last Zoom Icon: With this icon, the user can undo the last zoom.<br />
List Icon: With this icon, the user can create a numerical list of all values displayed on<br />
the graph.<br />
Export Icon: With this icon, the user can export the file.<br />
27
Many of these tools are also available on the graphing menu. Right-click on the graph to bring up the<br />
graphing menu.<br />
Use the mouse or arrow keys to select the graphing tools that you wish to use.<br />
6.2.4 Data analysis<br />
There are subtle differences in the graphs for each file type, but the base interaction with the graph will<br />
be consistent. The titles and legend are located above the graph. The information below the graph<br />
gives specific measurement and file information for the measurement variable that is highlighted by the<br />
cursor.<br />
28
Navigation through the graph<br />
The cursor can be moved from one measurement variable to another, and across the measurement to<br />
other time periods. You can use either the mouse or keyboard to navigate though the measurement<br />
variables.<br />
To navigate through the measurement values with the mouse:<br />
1) Move the mouse to a point on the graph.<br />
2) When the mouse is located directly over a point on the graph, the mouse cursor will change from an<br />
arrow (default) to a hand.<br />
3) Left-click on the measurement point to select the measurement variable.<br />
4) Note the actual measurement value and date/time stamp for the selected point, and move the<br />
mouse to another point on the graph.<br />
When there are a number of measurement variables occupying the same space on the graph, it is often<br />
difficult to differentiate between two different measurement variables on the graph. In these instances,<br />
it is often easier to use the arrow keys to navigate through the graph. Refer to the chart below for the<br />
keys available for navigation, and their specific function.<br />
Key Description Functionality<br />
Right arrow key Moves to the next data point of the measurement variable<br />
Left arrow key Moves to the previous data point of the measurement value<br />
Up arrow key Moves to the same data point of the previous measurement variable<br />
Down arrow key Moves to the same data point of the next measurement variable<br />
Home Home key Moves to the first data point of the measurement variables<br />
End End key Moves to the last data point of the measurement variables<br />
Pg Up Page up key Skips forward to a data point of the measurement variables<br />
Pg Down Page down key Jumps backward to a data point of the measurement variables<br />
29
Grouping data<br />
Grouping data into different time periods will affect the way information is displayed in the graph. This<br />
can help compare differences in the system from day to day or hour to hour. For example if the data is<br />
grouped by days, the graph will display data a day at a time on the screen. To move from day to day,<br />
the user can use the period navigation icons to move through the different graphs.<br />
To change the data grouping:<br />
1) Data can be regrouped to change the format of the graph using the shorter group or large group<br />
icons. The grouping can be changed from days to months using these icons.<br />
Shorter Group Icon<br />
Larger Group Icon<br />
2) Moving the mouse over either icon (without pressing the button) brings up text on what group will<br />
be created with that particular grouping icon.<br />
3) Continue pressing the icons until the desired grouping is accomplished, or until the data is grouped<br />
into the smallest or largest possible group.<br />
4) The new grouping may change the way the data is displayed on the graph. For example if the data<br />
is grouped by day, the software will plot a graph for each day of data.<br />
5) Use the period icons to move through the different period graphs to analyze the data. You can<br />
move to the previous or next period, or jump to the first or last period using the icons.<br />
6) Individual groupings can be printed or exported into other documents.<br />
30
Zooming in on data<br />
The software also gives the user the ability to zoom in on the data for a closer look. This makes it<br />
easier to look at the details of the graph, especially if the measurement variables have similar values.<br />
To zoom in on data:<br />
1) Move the mouse to the point on the graph that you would like to become the corner of the zoom<br />
view of the graph.<br />
2) Left-click the mouse, hold the button down and move the mouse until you have created a box<br />
around the area of the graph you would like to zoom in on.<br />
3) After the mouse button is released, the software will display only the information captured within the<br />
box that was created.<br />
4) Navigate through the information in the same way you would on the full screen view.<br />
5) Use the horizontal or vertical scroll bars to move through the graph without changing the view back<br />
to the full screen view.<br />
6) Repeat this process to zoom in further, or use the Zoom out icon to return to the full screen view.<br />

These energy studies will create a simple graph of all selected energy variables along the time axis.<br />
The grouping of the information can be changed to allow the user to see energy consumption by hour,<br />
day, month and year.<br />
40
Grouping data<br />
To change the data grouping:<br />
1) Data can be regrouped to change the format of the graph using the shorter group or large group<br />
icons. The grouping can be changed from days to months using these icons.<br />
2) Moving the mouse over either icon (without pressing the button) brings up text on what group will<br />
be created with that particular grouping icon.<br />
3) Continue pressing the icons until the desired grouping is accomplished, or until the data is grouped<br />
into the smallest or largest possible group.<br />
4) The new grouping may change the way the data is displayed on the graph. For example if the data<br />
is grouped by day, the software will graph the data for each day, showing one month’s data at a<br />
time. If it is grouped by hours, the software will graph the data for each hour, showing one day’s<br />
data at a time.<br />
41
5) Use the period icons to move through the different period graphs to analyze the data. You can<br />
move to the previous or next period, or jump to the first or last period using the icons.<br />
6) Individual groupings can be printed or exported into other documents.<br />
6.4 Quality studies<br />
With this analysis tool, the data is compared to a baseline standard to give a quick pass/fail result.<br />
Analysis will be performed on the voltage, harmonics, flicker or system imbalance. EN 50160, a<br />
European standard for power quality is available for comparison, but the user can create standards<br />
based on the requirements of the electrical systems or machinery.<br />
6.4.1 Create a quality study<br />

3) Use the mouse or arrow keys to scroll through the open files. Left-click the desired file and press<br />
the OK button to select a file.<br />
4) The viewer can be set up to display files that are grouped together. If no files appear, de-select the<br />
box next to Group files of same device.<br />
42
5) The file under test can be broken down into smaller groupings by left clicking on the down arrow<br />
next to the Group by field. Changing this field will change how the quality study is run. For<br />
example, a quality study on a file grouped by days will split the study into each individual day within<br />
the file and provide an analysis by day. This will allow the user to investigate individual days where<br />
the readings do not meet the applied quality standards.<br />
6) Left-click on the Setup tab to bring up the standard selection viewer.<br />
7) Left-click on an existing standard, or press the New button to create a new standard. Standards<br />
can also be modified to adjust them to your needs by pressing the Modify button.<br />
8) Make adjustments to any of the fields by either left-clicking on the field and typing in the text area,<br />
or by using the up and down arrows next to a field to adjust the value.<br />
43
9) The functionality of each of the fields is as follows:<br />
Header<br />
• Name: Name of the new standard<br />
• Description: Description of the new standard<br />
Voltage quality<br />
• % Of voltage OK: This is the minimum percentage of voltage values that must be met to be<br />
considered acceptable. For example if we have 95% of voltage OK, 95% of the file data must have<br />
a voltage within the set tolerances to be considered acceptable.<br />
• % Of maximum voltage: This sets the upper threshold of the voltage parameter. For example if<br />
the maximum is set at 10%. The voltage must remain below 110% of nominal to be considered<br />
acceptable.<br />
• % Of minimum voltage: This sets the lower threshold of the voltage parameter. For example if<br />
the minimum is set at 10%. The voltage must remain above 90% of nominal to be considered<br />
acceptable.<br />
• Force nominal voltage: This field forces the software to use the nominal voltage set up in the<br />
standard. If this field is unchecked, the software will try and collect a nominal voltage from the data<br />
file.<br />
• Nominal voltage: This is the voltage level that is desired by the standard. The minimum and<br />
maximum voltages are based on this number.<br />
• Discarded: Selecting this option will allow the software to select margins of values that will be<br />
discarded in order to calculate voltage quality. If it not selected all values will be considered.<br />
• +% Discarded: This is the upper base voltage percentage that must be met to calculate the<br />
voltage quality.<br />
• -% Discarded: This is the lower base voltage percentage that must be met to calculate the voltage<br />
quality.<br />
• Discard bad voltage: Selecting this option keeps bad voltages from being used to calculate<br />
voltage quality. If one value is bad in the period, or if the register is incomplete, the voltage will be<br />
discarded.<br />
Flicker quality<br />
• % flicker OK: Percentage of Plt samples that must be under the maximum Plt to be considered<br />
acceptable. For example if we have 95% of flicker OK, 95% of the file data must have a Plt less<br />
than the maximum Plt.<br />
• Maximum Plt: The Plt values in the file must be below this maximum to be considered acceptable.<br />
• Plt window: We can define a Plt window for files with Pst data.<br />
Harmonic quality<br />
• % Of harmonic OK: This is the minimum percentage of harmonic values that must be met to be<br />
considered acceptable. For example if we have 95% of harmonic OK, 95% of the file data must<br />
have harmonic measurements within the set tolerances to be considered acceptable.<br />
• Filter name: Select the harmonic filter that will be used as a baseline foe the data. The default<br />
setting is EN50160 standard, but the user can create standards for comparison.<br />
• Discard bad harmonics: Selecting this option keeps bad harmonic data from being used to<br />
calculate harmonic quality. If one value is bad in the period, or if the register is incomplete, the<br />
harmonic quality will be discarded.<br />
• Harmonic order: Select either the phase or individual harmonic to be the baseline for comparison.<br />
Imbalance quality<br />
• % Of imbalance OK: This is the minimum percentage of imbalance values that must be met to be<br />
considered acceptable. For example if we have 95% of imbalance OK, 95% of the file data must<br />
have measurements within the set tolerances to be considered acceptable.<br />
• Imbalance threshold (%): Maximum value of the unbalance coefficient (Kd) that is acceptable.<br />
• Discard bad imbalance: Selecting this option keeps bad imbalance data from being used to<br />
calculate imbalance quality. If one value is bad in the period, or if the register is incomplete, the<br />
imbalance quality will be discarded.<br />
10) After both the file and standard have been selected, press the Statistics button to create the quality<br />
study.<br />
44
11) Press the Cancel button to exit the viewer without creating a quality study.<br />
Note: If the Force nominal voltage option in the quality standard is not selected, the software will look<br />
for open files that have a designated nominal voltage. If none can be found, it will prompt the user with<br />
a warning message.<br />
Select a new standard, or modify the standard by selecting this option and repeat the “create a quality<br />
report” process.<br />
6.4.2 Data analysis<br />
The software will create a quality study based on all available data. The user can then analyze the<br />
results and dig deeper into the data in areas where the data failed to meet the applied standard.<br />
The quality study shown above gives a pass/fail indication of the file based on the data available to test.<br />
In the sample study above, the file met the requirements of the applied standard in voltage, flicker and<br />
harmonics. It was unable to test against the imbalance standard, because there was no imbalance<br />
data in the file.<br />
45
In the quality study shown above, the file was run against a standard created to match the results<br />
against the minimum voltage requirements to run the milling machines in the main plant without failure.<br />
Based on the report, the data filed to meet the requirements of the milling machine.<br />
The study can be broken down into smaller groups to get a better idea on why the test was failed. By<br />
breaking the grouping into days instead of weeks, the user can determine what day during the week<br />
that the failure occurred.<br />
To change the grouping of the quality study:<br />
1) Left-click on the configure icon, or right-click on the graph and select Configure from the graphing<br />
menu.<br />
2) The software will bring up the configuration viewer.<br />
3) The general tab of the configuration viewer lists the title and description of the applied study, the<br />
grouping and the large steps for navigating through the groupings.<br />
4) Left-click on the down arrow next to the Group by field. This will bring up a listing of the available<br />
grouping options.<br />
5) Left-click on the desired grouping and press the OK button. The software will automatically run the<br />
study with the new grouping.<br />
6) Press the Cancel button to exit the viewer without making a change.<br />
46
Running the study with a daily grouping showed that the voltage in the main plant failed to meet the<br />
minimum requirements on all three days of the test. Further analysis of the voltage will be necessary to<br />
determine what the problem was.<br />
6.4.3 Voltage studies<br />
Left clicking on the Voltage tab can do further analysis on the voltage. This will bring up detailed<br />
information on the voltage results form the selected result. The voltage study is in a pass/fail format to<br />
let the user know how the data matched up to the applied standard. A green check mark will be placed<br />
in front of results that met the standard, and a red x will be placed in front of results that failed to meet<br />
the standard.<br />
The voltage detail showed that the voltage quality on phases 1 and 3 were acceptable, but phase 2<br />
voltage did not meet the standard. The remaining groups (days in this example) can be checked by<br />
using the period navigation icons.<br />
47
To determine why the test failed, we can compare the test results against the applied standard.<br />
To review the voltage quality standard:<br />
1) Left-click on the configure icon, or right-click on the graph and select Configure from the graphing<br />
menu.<br />
2) The software will bring up the configuration viewer.<br />
3) Left-click on the voltage tab of the configuration viewer to review the voltage quality requirements of<br />
the applied standard.<br />
4) Make adjustments to any of the fields by either left-clicking on the field and typing in the text area,<br />
or by using the up and down arrows next to a field to adjust the value.<br />
5) Left-click on the desired grouping and press the OK button. The software will automatically run the<br />
study with the new voltage parameters.<br />
6) Press the Cancel button to exit the viewer without making a change.<br />
Our standard requires that 95% of the captured data fall within 10% of the nominal voltage. Based on<br />
our analysis, only 94.4% of the data fell within 10% of nominal. More detail on the individual data points<br />
may help us determine where improvements can be made.<br />
48
To get more detail on the failed test results:<br />
1) Double-click on the failed test.<br />
2) This will bring up a viewer with the voltage data from every recording period for the grouping. (Day<br />
1 of the file in our example)<br />
3) Use the vertical scroll bar, or the up and down arrow keys to scroll through the individual period<br />
results. A green check mark will be placed in front of results that met the standard, and a red x will<br />
be placed in front of results that failed to meet the standard. The individual phase will also be<br />
marked with an * to indicate the failure.<br />
4) Left-click on the Visualization settings to select/de-select which values will be displayed. You can<br />
choose to see only data points that passed, only those that failed, or both.<br />
5) The detailed information in this viewer can be printed, or exported into text by left clicking on either<br />

6.4.4 Harmonics studies<br />
A new analysis was run using the <strong>800</strong> series power analyzer to analyze the harmonic content of the<br />
power in the main plant. The quality study showed that level of harmonics did not meet the applied<br />
standard.<br />
Further analysis on the harmonic distortion can be done by left clicking on the Harmonic (%) tab. The<br />
harmonic study is in a pass/fail format to let the user know how the data matched up to the applied<br />
standard. A green check mark will be placed in front of results that met the standard, and a red x will<br />
be placed in front of results that failed to meet the standard.<br />
The harmonic study looks at both the total harmonic distortion, and the individual harmonics in order to<br />
compare them against the applied standard. In our analysis, the total harmonic distortion was a<br />
problem, as was the harmonic content in many of the individual odd harmonics.<br />
50
To determine why the test failed, we can compare the test results against the applied standard.<br />
To review the harmonic quality standard:<br />
1) Left-click on the configure icon, or right-click on the graph and select Configure from the graphing<br />
menu.<br />
2) The software will bring up the configuration viewer.<br />
3) Left-click on the harmonic tab of the configuration viewer to review the quality requirements of the<br />
applied standard.<br />
4) Make adjustments to any of the fields by either left-clicking on the field and typing in the text area,<br />
or by using the up and down arrows next to a field to adjust the value.<br />
5) Left-click on the desired grouping and press the OK button. The software will automatically run the<br />
study with the new voltage parameters.<br />
6) Press the Cancel button to exit the viewer without making a change.<br />
Our standard requires that 95% of the captured data fall within the harmonic requirements of EN 50160.<br />
Based on our analysis, many of the individual odd harmonics and the total harmonic distortion (THD)<br />
did not meet this standard.<br />
51
To get more detail on the failed test results:<br />
1) Double-click on the THD or individual harmonic test.<br />
2) This will bring up a viewer with the harmonic data from every recording period for the grouping.<br />
3) Use the vertical scroll bar, or the up and down arrow keys to scroll through the individual period<br />
results. A green check mark will be placed in front of results that met the standard, and a red x will<br />
be placed in front of results that failed to meet the standard. The THD or individual harmonic for<br />
each phase will also be marked with an * to indicate the failure.<br />
4) Left-click on the Visualization settings to select/de-select which values will be displayed. You can<br />
choose to see only data points that passed, only those that failed, or both.<br />

6.4.5 Imbalance studies<br />
Further analysis on imbalances can be done by left clicking on the Imbalance (%) tab. This will bring<br />
up detailed information on the imbalance results form the selected result. The imbalance study is in a<br />
pass/fail format to let the user know how the data matched up to the applied standard. A green check<br />
mark will be placed in front of results that met the standard, and a red x will be placed in front of results<br />
that failed to meet the standard.<br />
The imbalance study looks at unbalance coefficient (Kd) and compares it against the applied standard.<br />
In our analysis, the test results failed to meet our standard.<br />
To determine why the test failed, we can compare the test results against the applied standard.<br />
To review the imbalance quality standard:<br />
1) Left-click on the configure icon, or right-click on the graph and select Configure from the graphing<br />
menu.<br />
2) The software will bring up the configuration viewer.<br />
53

8. <strong>Power</strong>Vision file types<br />
The 805 and 806 power analyzers to save a wide variety of data that can be analyzed using the<br />
<strong>Power</strong>Vision software. The file extension for <strong>Power</strong>vision files is .STD. Contact technical support if<br />
you analyzer is saving alternative file types.<br />
.STD:<br />
Model 805 and 806 files<br />
The special analysis capabilities are described in the following sections of this instruction manual.<br />
9.1 STD files<br />
These files captured the standard power and energy data and harmonic distortion to either the 30 th or<br />
50 th harmonic. The additional analysis capabilities are enabled for the harmonic data within the file.<br />
Tables<br />
The software has the capabilities of creating tables for the voltage and current harmonics for each<br />
phase.<br />
Select a phase harmonics table from the table viewer. (See section 6.1 for more info on opening a<br />
table)<br />
The phase harmonics table gives the user the RMS for both current and voltage and displays the<br />
harmonic distortion both in its amplitude (in %THD) and its disphase (in degrees). The harmonic<br />
distortion information is then broken down into the individual harmonic to either the 30 th or 50 th .<br />
65
Graphs<br />
There are 4 additional graphs that can be created for files with harmonic data:<br />
• Wave forms<br />
• Harmonics graphic<br />
• Harmonic distortion<br />
• RMS<br />
These graphs can be created by selecting the harmonics category in the graph selector screen and<br />
then choosing the appropriate variable. In these graphs, only one variable may be selected. (See<br />
section 6.2.1 for additional information on creating a graph)<br />
Waveform graphs<br />
The screen for this graph is split into six sections to display the voltage and current waveforms for each<br />
phase. Information for the voltage phases is listed above the voltage waveforms in the top three<br />
sections, and the information for the current phases is listed below the current waveforms in the bottom<br />
three sections.<br />
66
Waveforms will be created for each period in the file. Use the period navigation icons to navigate<br />
through the graphs for each period.<br />
Harmonic graphic<br />
The screen for this graph is split into two halves. The top half displays the harmonic content of the<br />
voltage and the bottom half displays the harmonic content of the current.<br />
The default setting for this graph is a bar graph, where the harmonic value of each individual phase (for<br />
both current and voltage) is plotted to either the 30 th or 50 th harmonic. This allows the user to see at a<br />
glance the level of distortion on each harmonic.<br />
Separate bar graphs will be created for each period in the file. Use the period navigation icons to<br />
navigate through the graphs for each period.<br />
67
Harmonic distortion<br />
The screen for this graph is split into two halves. The top half displays the %THD of the voltage and the<br />
bottom half displays the %THD of the current.<br />
The default setting for this graph is a bar graph where the %THD of each individual phase (for both<br />
current and voltage) is plotted for each time period within the file. This allows the user to see at a<br />
glance the amount of distortion in the file, and how it changes over time.<br />
RMS Graphic<br />
Much like the THD graph, the RMS graph is split into two halves. The top half displays the RMS value<br />
of the voltage and the bottom half displays the RMS value of the current.<br />
The default setting for this graph is a bar graph where the RMS value of each individual phase (for both<br />
current and voltage) is plotted for each time period within the file.<br />
68
Harmonic filtering<br />
For both the harmonic graphic and harmonic distortion graph, the user has the ability to apply a filter to<br />
the harmonic level. This filter will create a baseline on the graph to allow the user to quickly see if the<br />
level of harmonic distortion is greater than the user selected values.<br />
To activate the harmonics filter:<br />
1) Left-click on the harmonics filter icon, or right-click on the graph and select properties from the<br />
graphing menu.<br />
2) The software will bring up the harmonics filter viewer.<br />
3) The user can apply any of the filters in the list be selecting the filter and pressing the Apply button.<br />
4) To modify a filter, select a filter and press the Modify button.<br />
5) To create a new filter, press the New button.<br />
6) To delete a filter from the list, press the Delete button.<br />
7) If the user chooses to create a new filter, or modify an existing one, the software brings up the filterediting<br />
box.<br />
69
8) Use the mouse to select each field in the editor and type in the name of the filter, the maximum<br />
voltage and current THD values and the maximum harmonic values for each of the individual<br />
harmonic values to the 50 th harmonic.<br />
9) Press the OK button to save the values entered into the filter.<br />
10) Press the Cancel button to close the viewer without creating or modifying a filter.<br />
11) Select the new filter and press the Apply button to activate the new filter.<br />
12) Press the Cancel button to exit the filter viewer without activating a filter.<br />
For harmonic graphs, the filter will create a baseline for each individual harmonic on top of the entire<br />
graph allowing the user to quickly see if any values fell above the baseline values.<br />
For harmonic distortion graphs, the filter will create a baseline for the THD values on top of the entire<br />
graph allowing the user to quickly see if any THD values fell above the baseline value.<br />
