No harmonic mitigation solution is ideal for every application. So, once you or your client decides to reduce harmonic distortion on a facility electrical power system, you must consider several ...

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 ...

A variable frequency drive (VFD) fails to vary the discharge-air fan speed. A motor overheats and fails prematurely. Programmable controls that generally operate without issue suddenly experience ...

Power quality and harmonics have been a developing and growing concern as buildings have become more reliant on technology, the ever-increasing utilisation of digital control systems, and the drive ...

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