HARMONIC FILTER RESISTOR

Ever increasing usage of solid state devices like VFD drives and Thyristor controlled Electrical Furnaces etc causes distortion of waveforms with higher frequency Harmonics in supply system resulting in poor quality of power to end users. Harmonic filters are designed to bypass unwanted frequencies using combination of Reactor, Capacitors along with Resistor to achieve better quality power. We specialize in manufacturing medium voltage Filter Resistors for various applications starting from 11 kV onwards.
