Harmonic Filter Reactors
Power transmission and distribution systems are designed for operation with sinusoidal voltage and current waveforms at a constant frequency. However, when non-linear loads – such as thyristor drives, converters and furnaces – are connected to the system, excessive harmonic currents are generated, and this causes both current and voltage distortion.
Harmonic filtering is the best way to eliminate this distortion from the power system, while at the same time producing reactive power.
