Shunt 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. The net result is improvement in power factor. (ii) Shunt inductive compensation.
