Setting the Measurement Time
The measurement time is the time between the start of the measurement to the end of
the measurement. The time for measuring harmonics is set in units of 1 s in advance.
The harmonics can be measured continuously for the specified time. The measurement
time can be changed when equipment that emits harmonics that fluctuate over time is
measured or when confirming that the emitted harmonics do not change even when the
equipment is operated over extended time.

One set of harmonic measurement data (handled as instantaneous values by the
software) consists of harmonic data measured every 200 ms (10 cycles for 50 Hz and
12 cycles for 60 Hz). The instantaneous values, the mean value, and the maximum
value of the measured data retrieved within the measurement time (see next page)
can be evaluated to determine whether they are within the limits of the standard.
• When in Off-Line Mode
Evaluation can be made on the loaded measurement data according to the method

Harmonic Preview
You can only select Harmonic preview in online mode. As the WT measures the harmonic
current, you can observe the harmonic fluctuations as they appear on a list of measured
values. Unlike the compliance test, the harmonic preview is only for observing the state
of a harmonic current. It does not determine whether or not a device conforms to certain
standards. New data replaces old data. The software only retains the most recently
acquired values.

Starting/Stopping Measurements
• Compliance Test
After you start WT harmonic current analysis from your PC, the PC will acquire
and save the values that the WT measures. All of the data that is acquired during
the specified measurement time is saved. After the specified measurement time is
reached, the PC will automatically end measurement and data acquisition. You can
also stop data acquisition from the PC before the measurement time is reached.

mode.
Display of the Evaluation Result within the Entire Measurement Time
Evaluation can be made as to whether all of the harmonic measurement data in the
measurement time are within the limits according to the settings specified in “Setting the
Standard and Measurement Environment” (as described earlier), and the results can be
displayed collectively.
List and Bar Graph Displays of In and I1
The software displays the measured values of In and I1 and the standard limits of those
values for each harmonic order in both a list and a bar graph. You can use colors to
indicate whether a value is under its limit or not. The software judges based on the average,
maximum, and instantaneous values that are acquired in a period of measurement
(instantaneous values are the values that are acquired at each measurement of the
harmonic current).

Terminology Related to Harmonics
Harmonics refer to sine waves whose frequency is an integer multiple of the fundamental
wave (normally sine waves of commercial frequency 50-Hz or 60-Hz) excluding the
fundamental frequency.
Fundamental Wave (Fundamental Component)
The sine wave with the longest period among the different sine waves derived from the
periodic complex wave. Or the sine wave that has the fundamental frequency within the
components of the complex wave.
Fundamental Frequency
The frequency corresponding to the longest period in the periodic complex wave. The
frequency of the fundamental wave.
Distorted Wave
A wave that differs from the fundamental wave.
Higher Harmonic
A sine wave with frequency that is an integer multiple (twice or greater) of the
fundamental frequency.
Harmonic Component
Waveform component with frequency that is an integer multiple (twice or greater) of the
fundamental frequency.
Harmonic Order
Integer ratio of the harmonic frequency with respect to the fundamental frequency. IEC
defines the maximum harmonic order that is measured to be 40.
PLL Source
When measuring harmonics, the fundamental period (period of the fundamental signal)
must be determined in order to analyze the higher orders. The PLL (Phase Locked Loop)
source is the signal that is used to determine the fundamental period.
THC (Total Harmonic Component)
Sum (rs value) of harmonic currents of orders 2 to 40.

System impedance (Z), and rated line current (Iequ)
You can set the system impedance (Z) and the rated line current (Iequ) within these
ranges:
• System impedance (Z): 0.01 to 1000 Ω
• Rated line current (Iequ): 0 to 1000 A

If you set the rated line current (Iequ) to a value greater than 20 A, in order to keep the
voltage drop caused by the input impedance of the current input circuit to 0.15 Vrms or
less, use a current sensor to measure the current rather than directly connecting the
current to the WT. Set the WT current range and sensor ratios according to the procedure
in section 7.2.

Measurement Time
11
The measurement time is the time between the start of the measurement to the end
of the measurement. The time for measuring harmonics can be set in advance. The
harmonics can be measured continuously for the specified time. The measurement
time can be changed when equipment that emits harmonics that fluctuate over time is
measured or when confirming that the emitted harmonics do not change even when the
equipment is operated over extended time.
Selectable range: 0 H 0 M 1 S to 24 H 0 M 0 S in units of 1 s.
• An error occurs if a time exceeding 24 hours is specified.
• If you set the measurement time to 0 H 0 M 0 S and begin measurement,
measurement will continue until you click Stop Test in the Measure submenu or press
the stop test icon in the tool bar.
Note
Depending on the environment of the PC onto which this software was installed, an error
occurs if you specify a time longer than the memory area that can be reserved. In this case,
you may be able to increase the available time by exiting other applications or by increasing the
amount of memory available to the PC.

select to display average, maximum, or instantaneous values. This section explains the
differences between each display.
• Average Value Display
• Values and bars for each harmonic order
The software averages the measured data of each harmonic order acquired within
the measurement time and displays those averages.
• Measured items that appear to the right of the list
The software averages the values acquired for each measured item within the
measurement time and displays those averages.
• Limit values and bars
The software displays numbers and yellow bars that indicate the values of the
limits.
• Maximum Value Display
• Values and bars for each harmonic order
The software finds and displays the maximum value from each harmonic order’s
measured values by comparing the instantaneous values that have been acquired
within the measurement time.
• Items that appear to the right of the list
The software finds and displays the maximum value for each measured item
by comparing the instantaneous values that have been acquired within the
measurement time.
• Limit values and bars
The software displays numbers and yellow bars that are 1.5 times greater than the
values of the limits.
Note
Using the scroll bar will have no effect on the Rsce list and bar graph displays.
Bar Display Colors
The lengths for the bar graphs are determined by the size of the measured data that they
represent. The meanings of bar colors are as follows:
Blue
Does not exceed the limit.
Red
Exceeds the limit.
White
A limit has not been specified.
Yellow
The limit specified by the standard.
* The colors and corresponding names are the same as those in Microsoft Word and
Microsoft Excel.

Select A, V, or Deg (for current, voltage, or phase angle).
Explanation
Bar Graph of Harmonic Current or Voltage
The software displays the instantaneous values acquired within the measurement time
for each harmonic order.
Bar Graph of Harmonic Phase Angles
Bar graphs of the phase angle of the harmonic current with respect to the fundamental
current for each order can be displayed. However, the phase angle with respect to the
fundamental voltage is displayed on the bar graph for the fundamental current.
• When the harmonic phase is leading the fundamental current, a positive phase angle
is indicated; when the harmonic phase is lagging the fundamental current, a negative
phase angle is indicated.
• When the fundamental current is leading the fundamental voltage, a negative phase
angle is indicated; when the fundamental current is lagging the fundamental voltage, a
positive phase angle is indicated.
Bar Graph Display Color
The bar graph is displayed in white.
Note
This bar graph does not display limits, because there are no current, voltage, or phase angle
limits.

Problems and Solutions
If you cannot connect to the WT3000 via GP-IB:
A GP-IB connection made to the WT may not work properly if the GP-IB card that is used is not made by NI
(National Instruments). We recommend that you use a National Instruments GP-IB card (see section 1.2).
Measurement stops suddenly.
Close the memory-resident software running on the PC. For example, if virus checking software frequently
checks the communications between this software and the PC, the performance of the PC may decline
drastically. If you choose to stop the virus check and use the PC, please do so in a network environment
that is well protected against viruses.

Measurement modes*
• Compliance testing
• In online mode
Measures the harmonics of the data acquired from the WT, and judges those harmonics
based on IEC 61000-3-12 First Edition.
• In offline mode
Judges the measured data loaded from a file according to IEC 61000-3-12 First Edition.
• Harmonic preview
Only available in online mode. As the WT measures the harmonic current, the harmonic
fluctuations appear on a list of measured values.
• Waveform preview
Only available in online mode. The measured waveform appears as it is measured on the WT.
Standard and measurement settings
Judgment conditions configurable in accordance with IEC 61000-3-12 Edition 1.
Measurement time
The time from the start to the end of measurement.
Measurement time can be set in one-second intervals within the range of 0 h 0 min 1 s to 24 h 0
min 0 s.
Report titles/comments
Report titles and comments can be entered. Report formats: color/black and white; English/
Japanese. Reports are printed and saved to .bmp or .pdf files along with measured data.
Measure start/stop
Measurement can be started in online mode.
Display of judgment results, measured data, and waveform data
When a compliance test is performed, the software will display judgments as to whether or not
the data complies with IEC 61000-3-12 Edition 1, along with the measured data and waveform
data that was judged.
• Display of all judgment results within the measurement time
Determines whether or not all of the data within the measurement time is within the set
limits, and displays the result.
• In/I1 list and graph display
Displays the measured values of In/I1 for each measured harmonic and the limits set by the
standard for those values in both a list and a bar graph.
• Rsce list and graph display
Displays the measured values of Rsce for each measured harmonic and the limits set by the
standard for those values in both a list and a bar graph.
• Bar graph display of harmonic voltage, current, and phase angle
Displays the measured data for each harmonic in a color-coded bar graph.
• List display of harmonic voltage, current, and phase angle values
Displays the measured data for each harmonic in a color-coded list.
• Trend graph display
Displays a graph that shows data fluctuations over time.
• Waveform display of voltage and current
Displays a waveform of data measured immediately after the measurement time (displays
approximately two waveform periods).
