HSD Filter Overview
The HarmonicShield
®
(HSD) Filter provides a low impedance path for the major harmonic currents demanded
by Variable Frequency Drives (VFDs). This greatly reduces the amount of harmonic currents flowing through
the electrical power distribution system, bringing those harmonic currents in line with the IEEE-519 standard
for harmonic distortion mandated by an increasing number of utilities.
