761922 Harmonic Analysis Software for WT3000/WT3000E (Upgrade Version)


The 761922 harmonic/flicker measurement software allows you to load data measured by the WT3000/WT3000E onto a PC and perform harmonic measurements conforming to IEC61000-3-2 Ed4.0. The WT3000/WT3000E supports the 50/60 Hz (10/12 cycles) of interharmonic measurement required by IEC61000-4-7 Ed2.0 Am1, which may become a requirement for standards measurement in the future.

The measurement procedure required by the international standard for harmonic current suppression, IEC 61000-3-2 Ed. 3.0, has been amended. The standard requires harmonic and interharmonic measurement supporting window widths of 50 Hz/60 Hz, 10/12 cycles.

Support of the IEC 61000-4-15 Ed1.1 /Ed2.0.
The flicker meter standard that defines the requirements of the measurement equipment and test method of voltage fluctuation and flicker measurement.

Support of the IEC61000-3-3 Ed2.0 and Ed3.0
The measurement and judgment procedure of the Voltage fluctuation and Flicker requires above international standards as well.
