Shunting capacitor
WebDuring the switching on/off of shunt capacitor banks in substations, vacuum circuit breakers (VCBs) are required to switch off or to switch on the capacitive current. Therefore, the VCBs have to be operated under a harsh condition to ensure the reliability of the equipment. This study presents a complete comparison study of ordinary and phase-controlled VCBs on … WebAnswer (1 of 2): Shunt capacitor and shunt reactor both are used in power system to improve it’s performance. Since capacitor provides leading power factor and hence it used at such places where poor lagging power factor is undesirable. Shunt capacitor is mainly used in parallel with devices oper...
