Medium Voltage Metal Enclosed Harmonic Filter Banks are custom designed for application on industrial, commercial, and utility power systems that require medium voltage power factor correction, var and voltage support, and mitigation from harmonic resonance or harmonic distortion. The harmonic filter banks are configurable as fixed or automatic controlled with 1 or more stages at voltages from 2.4kV through 38kV.

ZDDQ Low voltage metal enclosed capacitor and filter banks improves power factor in systems with variable energy demand and non-linear loads, therefore, with variable reactive load needs. Low voltage metal enclosed capacitor and filter banks,equipped with a power factor controller to regulate their automated operation and monitoring features, ZDDQ automatic capacitor banks remove power factor charges of the electricity bill and reduce the losses of electrical equipment and wiring by power factor improvement and harmonics filtering.
