One of the most often mentioned and misunderstood power quality issues we see with commercial, industrial, and power-generating electrical equipment is harmonics. Since it’s impossible to explain the ...

This article is part of a multi-part series on how to identify, monitor, diagnose, and deal with harmonics in electrical power systems. Last month’s column discussed how to take the data gathered when ...

The steady increase in non-linear loads on the power supply network such as, for instance, variable speed motor drives (VSDs), raises questions about power quality and reliability. In this respect, a ...

Rectifier systems play a critical role in the conversion of alternating current (AC) to direct current (DC) in a variety of applications including industrial drives, renewable energy integration, and ...

Despite the name, electrical harmonics are terrible for data center harmony. In a perfect world, the power supply feeding a data center would produce a smooth, sinusoidal waveform at one constant ...

The PM6000 power analyzer from Voltech has gained independent certification of accuracy for inter-harmonics measurements to IEC61000-3-2, the international product-compliance standard for current ...

If the electronic device you are developing plugs into the wall for power, chances are that you will need to send it to a compliance lab to ensure it meets a variety of international standards such as ...
