Harmonic/flicker measurement software complies with updated standards
Article Type: Equipment and software From: Aircraft Engineering and Aerospace Technology: An International Journal, Volume 80, Issue 4
A new version of the harmonic/flicker measurement software for the Yokogawa WT3000 precision power analyser has been released to comply with new international power-quality standards.
The new 761922 harmonic/flicker measurement software has been developed in response to new regulations for harmonic current over 16 A, which will be enforced as a low-frequency EMC test from February 2008. The relevant new standards, which include precise definitions of measurement procedures and settings, are EN61000-3-11/IEC61000-3-11: limitations of voltage fluctuations and flicker – equipment rated current >16 A per phase; and EN61000-3-12/IEC61000-3-12: limits for harmonic current emissions – equipment rated current >16 A per phase.
The upgraded harmonic/flicker measurement software allows engineers without specialised knowledge to perform a range of operations using the WT3000 precision power analyser, including value limit judging functions for standards compliance and the production of test reports.
The software requires the WT3000 precision power analyser to be fitted with the 30 A input option as well as the advanced computation and flicker measurement functions.
The Yokogawa WT3000 precision power analyser provides “best in class” precision and stability. With a basic power accuracy of ±0.02 per cent of reading, DC and 0.1 Hz-1 MHz measurement bandwidth, and up to four input elements, the WT3000 provides a high-accuracy measurement solution for testing all types of power electronics products.
