Shunt capacitance
WebShunt inductive compensation. This method is used either when charging the transmission line or when there is very low load at the receiving end. Due to very low or no load, a very low current flows through the transmission line. Shunt capacitance in the transmission line causes voltage amplification ( Ferranti effect ). WebJan 10, 2024 · Shunt capacitive compensation. This method is used improve the power factor. Whenever an inductive load is connected to the transmission line, power factor lags because of lagging load current. To compensate it, a shunt capacitor is connected, which draws current leading to the source voltage.
