Harmonic distortion is the one playing the major role among them.
Abilities include measurement of Total Harmonic Distortion (THD) over the complete 20Hz to 20kHz audio band, as well as measurement over a wide input range (up to 750Vrms) and has low residual distortion (-87dB).
According to Saftronics' specialist, John Cherney, harmonic distortion shows up as electrical noise on a power distribution network.
These currents, known as harmonic distortion disturb the voltage quality on the power line causing a variety of disturbances within an affected facility.
All of the gen-sets include Gillette's Kleen-Power power conditioning design, which yields an average of 7 percent harmonic distortion and no more than 125 total TIF.
So it is necessary to reduce those harmonic distortion in the supply voltage by providing filters.
A new harmonics calculation option for the MDA800 motor drive analyzer series enhances the standard capabilities of the software by adding advanced harmonic filtering for AC input and drive output numeric table measurements; total harmonic distortion measurement parameters for voltage, current, and power; and a new harmonic order table with spectral waveform displays.
The text in this paper has been supported through data of the real time power signal analysis to quantify total harmonic distortion (THD), inter harmonics and comparative analysis of frequency spectrum of different UPS.
They are said to provide the lowest total harmonic distortion and jitter in their class.
The recent introduction of the Ranger PM7000 power-quality analyser from OUTRAM RESEARCH has enhanced and simplified the way in which PQE carries out on-site measurements of harmonic distortion, supply interruptions and load-profiles.
Operating at 85 percent efficiency, the devices incorporate active power factor correction to minimize input harmonic distortion and the switchers accept input from 85-264VAC or 120-320VDC.
