Chapter 1 Product Overview

1-2 IM 761922-06E

You can start this software and then operate it according to the order of one of the test schedule menus. By designing appropriate menus, you can make the testing process smoother. You can also avoid forgetting and skipping steps when you have to repeat the same process over and over again.Here are more details about each step:

Start

Select and edit test schedule menus. There are five preset standard menus available in additiontocustommenusthatyoucanmakeyourself(locatedunderthe“UserSetting”option button).

Open

Loading Setting InformationYou can load setting information files that contain information such as the measurement mode, bar graph and list display formats, standard and measurement settings, the measurement time, and report titles and comments (reports contain information such as judgmentresultsandlistsandgraphsofmeasureddatavalues).

Loading Measured Data and Waveform DataYou can load the harmonic measurement data, waveform data, harmonic measurement conditions, and setting information that have been saved to a file.

Connection

UsetoconnectthePConwhichthissoftwareisinstalledtoaWTthroughaGP-IBorEthernet interface.

Setting

Standard and Measurement SettingsYoucansetjudgmentconditionsaccordingtotheIEC61000-3-2orJISstandard.

Setting the Measurement TimeThe 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.

Measures the harmonics using the measurement conditions entered according to the applicable standard

Measurement 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.

* ForwhentheIEC61000-4-7editionissetto2.0or2.0A1.WhentheIEC61000-4-7edition is set to 1.0, the number of cycles is 16 (320 ms at 50 Hz or 267 ms at 60 Hz).

• When in Off-Line Mode Evaluation can be made on the loaded measurement data according to the method

complyingwithIEC61000-3-2orJIS.

Test PreviewYou can only select Test preview in online mode. As the WT measures the harmonic current, you can observe the harmonic fluctuations as they appear on a list and bar graphs of measured values. You can also observe the measured waveform.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.

Harmonic current can be displayed for each input element of the WT.

Bar Graph Display of Harmonic Voltage, Current, and Phase AngleYou can display the measured data for each harmonic in a bar graph. The software will display the instantaneous values in the bar graph (instantaneous values are the values that are acquired at each measurement of the harmonic current).

List Display of Harmonic Voltage, Current, and Phase AngleYou can display the measured data for each harmonic in a list. The software will display the instantaneous values in the list (instantaneous values are the values that are acquired at each measurement of the harmonic current).


1-6 IM 761922-06E

Trend Graph Display of Harmonic MeasurementsFor each harmonic, you can use a trend graph to show how the harmonic measurement data fluctuates over time.

Waveform Display of Voltage and CurrentYou can display a waveform that is measured immediately after the measurement time finishes. The software will display approximately two waveform periods. You can click on an area to display a cursor and show the instantaneous values there.

Repeatability of Measured DataThe mean value in the harmonics measurement data saved to files can be compared, and the difference in the measured data can be displayed on a bar graph or numerical list for each order. This function can be used to evaluate whether the difference between data measured under the same measurement conditions when harmonics are measured using the same product or same product model is within ±5% of the limits (confirmation of repeatability).

1.5 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 FrequencyThe frequency corresponding to the longest period in the periodic complex wave. The frequency of the fundamental wave.

Distorted WaveA wave that differs from the fundamental wave.

Higher HarmonicA sine wave with frequency that is an integer multiple (twice or greater) of the fundamental frequency.

Harmonic ComponentWaveform component with frequency that is an integer multiple (twice or greater) of the fundamental frequency.

Harmonic OrderIntegerratiooftheharmonicfrequencywithrespecttothefundamentalfrequency.IECdefines the maximum harmonic order that is measured to be 40.

PLL SourceWhen 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.

k = 2

I(k): rms current of each orderk: harmonic order

Measurement TimeThe 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.

NoteDependingontheenvironmentofthePContowhichthissoftwarewasinstalled,anerroroccurs if you specify a time longer than the memory area that can be reserved.

• Condition 1 The maximum harmonic current over the measurement time is within 1.5 times the

specified limit. Evaluation is made on each order.

• Condition 2 The mean harmonic current over the measurement time is within the specified limit.

Evaluation is made on each order.

• 200% Short-Term Relaxation Conditions If all of the following conditions are met, up to 200% of the specified limits is permitted.

• TheEUTbelongstoClassAforharmonics.• The excursion beyond 150 % of the applicable limits lasts less than 10 % of the test

Click to zoom out. You can zoom out until the trend display area contains the data for all of the elapsed time.

Scroll bar You can drag (the slider) with the mouse or click to select the measured data that you want to display.

CursorWhen you click somewhere on the trend display area, a cursor will appear there.You can move the cursor by dragging it.

SliderMove along the time axis to the waveform that you want to display.

PP_Max In the trend display, if not all the measured values can be displayed because the specified time axis value is set too high, measured values are P-P compressed and displayed.* When this occurs, PP_Max is displayed here. To display values without P-P compression, zoom in on the time axis.

* P-P Compression (Peak-to-Peak Compression)In P-P compression, a maximum and minimum value are extracted from the values measured over a given period of time and are used to produce a compressed measured value.For details, see section 2.7 of the WT3000 or WT3000E User’ s Manual.• WT3000: IM760301-01E• WT3000E: IMWT3001E-01EN
