Non-linear loads such as variable frequency drives (VFDs) increase efficiency; however, they significantly pollute the power quality of the site and grid by introducing substantial harmonic current distortion (THD-i).
The addition of a CTM GridDefender Passive Harmonic Filter reduces harmonic current distortion below 5%, ensuring compliance with IEEE-519 and protecting other on-site equipment. Furthermore, GridDefender filters perform well under partial load conditions, are generator compatible, and do not require drive control of capacitor contactors (simply customer connections).
