What is the effect of series capacitor in a circuit?

Due to the effect of series capacitor the receiving end voltage will be instead of VR as seen from the phasor diagram (Figure 2). Thus with series capacitor in the circuit the voltage drop in the line is reduced and receiving end voltage on full load is improved. Series capacitors improve voltage profile.

The objective of series capacitive compensation is to vary (or reduce) the overall effective series transmission reactance between the sending and receiving ends. Thyristor-controlled series capacitor (TCSC) provides variable series capacitive compensation using the thyristor firing (or delay) angle control.

What is a series capacitor used for?

Control of voltage. Series capacitors are used in transmission systems to modify the load division between parallel lines. If a new transmission line with large power transfer capacity is to be connected in parallel with an already existing line, it may be difficult to load the new line without overloading the old line.
