What is Series Compensation? Advantages & Location of Series Capacitors …
Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. Thus, it improves the power transfer capability of the line. Series capacitors …

Following this rule, when load 1 is turned on, capacitor bank 1 becomes active to provide compensation. Further as load 2 turns on, capacitor bank 2 also turns on along with 1 to provide compensate the dip in the power factor. Therefore, when both the loads are switched in the circuit, all the capacitor banks are active thus providing full
