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 ...

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 ...

NEW BERLIN, Wis. - "If you claimed that the sole purpose of a variable speed motor drive was to increase energy efficiency, it would be no exaggeration, of course," said Mike Olson, HVAC sales manager ...

TORONTO, ONTARIO--(Marketwired - Sep 22, 2015) - A new whitepaper from harmonics solutions provider MIRUS International shows that a properly designed passive harmonic filter has significantly greater ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Determine if a VFD is right for your application. The primary function of a variable frequency drive is to vary the ...

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 ...

Voltage distortion If a VFD were “perfect,” the voltage and current signals being provided to the motor would be perfectly sinusoidal. However, since some distortion always occurs during rectification ...

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 ...

This paper was first presented at the Gas Machinery Research Council 2021 Gas Machinery Conference in Louisville, Kentucky in October 2021. Because of the original length of the paper, it has been ...
