Thyristor Switch is an electronic power unit which can switch on/off the shunt capacitors fast. Its main loop adopts anti-parallel thyristor module. It supports level and pulse control ways which is suitable for low voltage capacitor fast switch on/off.This thyristor Switch can be used while power grid system harmonic distortion is high or in LC reactive filter installations.
