Harmonic Filter Capacitor Bank
A Harmonic Filter Capacitor Bank is a specialized device designed to provide reactive power compensation while simultaneously mitigating harmonics in electrical power systems. Unlike conventional capacitor banks, a Harmonic Filter Capacitor Bank combines capacitors with series-connected reactors to create a tuned filter that absorbs specific harmonic frequencies. This dual function makes a Harmonic Filter Capacitor Bank an essential solution for industries with sensitive equipment and non-linear loads.
Function of Harmonic Filter Capacitor Bank
The primary function of a Harmonic Filter Capacitor Bank is twofold: to improve power factor and to reduce harmonic distortion. Modern electrical systems often suffer from harmonics due to variable frequency drives, rectifiers, and other electronic equipment. A Harmonic Filter Capacitor Bank addresses this issue by filtering out targeted harmonic currents while supplying reactive power, thus ensuring stable voltage and improved power quality.
Design and Components of Harmonic Filter Capacitor Bank
A Harmonic Filter Capacitor Bank is typically built with:
-
Capacitor Units for reactive power support.
-
Series Reactors that tune the bank to specific harmonic frequencies.
-
Switchgear and Protection Devices for safe operation.
The design of a Harmonic Filter Capacitor Bank is customized depending on the harmonic spectrum and the reactive power requirements of the facility.
