The measurement procedures and settings for harmonic/flicker standards testing have been precisely defined. Engineers must also stay current with the specialized knowledge and uptodate information required to periodically review the contents of the standards and perform the standards conformance tests. The model 761922 Harmonic/Flicker Measurement Software enables engineers without specialized knowledge to perform a range of operations using the WT3000/WT3000E Precision Power Analyzer including judging standards compliance and outputting test reports.

Harmonic Current Measurement Value List
Displays harmonic measurement data as a single list.
Viewing Trends
You can capture various types of data measured into your PC at 200ms fixed intervals. Thus, you can view trends graphically. This feature lets you monitor power supply voltage fluctuations, changes in current consumption and other timebased variations.
Harmonic Current Measurement Value List
Displays harmonic measurement data as a single list.
Harmonic Current Bar Graph
Evaluates whether harmonic data is within the standard limit value, and displays the result as a bar graph. The display of evaluation results is colorcoded, in colors such as red and blue.^{2}
Waveform Observation
Lets you display voltage or current signal waveforms, and measure frequencies and peak values. Moving the cursor lets you display values for the displayed waveform.
2:Evaluations conforming to the IEC6100032 Ed. 4.0
Automatic Report Generation
You can print harmonic measurement results as value lists and graphs, and save image data. Titles and comments can be entered in reports, letting you enter information such as measurement dates/times, device names or control numbers.
You can enter settings on the WT3000/WT3000E from your PC. The wiring method, filters, and scaling settings can be modified.
Waveform data and harmonic current values can be saved on the PC. Measured data can be saved to .csv files for easy access by spreadsheet programs such as EXCEL.
Voltage fluctuation and flicker measurement complying with IEC 6100033 is executed. Calculates all the voltage fluctuation and flicker values of dc, dmax, d(t), Pst, and Plt, compares them to the preset limits, and indicates the total judgment.

dmax  :  Maximum relative voltage change 
Tmax, d(t)  :  Period during which relative voltage change exceeds the threshold level 
idc  :  Instantaneous relative steadystate voltage change 
idmax  :  Instantaneous maximum relative voltage change 
id(t)  :  Period during which instantaneous relative voltage change exceeds the threshold level 
PF  :  Instantaneous flicker sensation (IFS) 
Displaying the CPF Graph
You can select the element and color to be displayed on the CPF graph.
Up to four elements can be displayed simultaneously.
You can set a separate color for each element.
Printing
You can create reports using the data measured with the software.

Three Measurement Modes (during online operation)
1. Harmonic Measurement Mode
Can evaluate measurement data while harmonics are being measured by a WT3000/WT3000E.
NOTE: Saved measurement data can also be read and displayed during offline operation.
2. Harmonics Observation Mode
Lets you observe harmonic variations as bar graphs or lists of numerical values, while harmonics are being measured by a WT Series digital power meter. Use this mode to observe changes in harmonic data.
3. Waveform Observation Mode Lets you observe measured waveforms. Use this mode to observe waveform states.
Can evaluate * data by class (A, B, C or D). Can evaluate whether the current value is within the maximum permitted harmonic current limit value (or within the power ratio limit value).
Lets you measure the harmonic current over a set amount of time. Can evaluate whether the result is within the limit value.*
Maximum values and average values in harmonic measurement data can be compared and measurement data differences can be displayed as bar graphs and numerical values for each harmonic order saved. This mode lets you evaluate* whether values are within the 5% range specified by the standard (repeatability).
*Evaluations conforming to the IEC6100032 Ed. 4.0 are only supported by WT3000/WT3000E.
Harmonic measurement system configuration
*3: Many AC Power Sources are available to provide the lowdistortion AC Voltage and frequency to power the device under test. In addition, for fullcompliance testing, the power source must be capable of supplying the full 16 A load current specified by the IEC standard. Contact your local Yokogawa representative for recommendations.*4: The model that full supports the standard is the WT3000/WT3000E.
