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 ...

Reactors for AC drives are available as either AC reactors or DC reactors (DC link chokes). Both serve the same main purpose: to smooth the current flow to the AC drive, and reduce damaging harmonics ...

SOLV harmonics analysis software is a powerful simulation program that calculates current and voltage distortion levels in variable-frequency-drive (VFD) systems and provide Mirus Lineator harmonic ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed elevating the frequency of power pulses/sec fed to motors for faster Increasingly common, variable frequency ...

With the rising demand of non-linear type equipment and loads, mitigation of harmonics becomes increasingly important. If a harmonics study or testing indicates excessive harmonic levels or a ...
