If you're installing a variable-frequency drive (VFD) or uninterruptible power supply (UPS) — or if you already have this equipment in place — you should be monitoring certain power quality parameters ...

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 ...

Harmonic is one of the most important concepts on the power system that cannot be neglected since it can affect the power quality and operation of equipment. High levels of Harmonics in the system may ...
