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
Starting capacitor. The capacitor used to start single-phase induction motors is called a starting capacitor. When a capacitor is connected in series with the start winding of a single-phase motor, it creates a phase shift between the current in the start winding and the main winding. This phase shift causes the motor to rotate in the desired

Control of Voltage – In series capacitor, there is an automatic change in Var (reactive power) with the change in load current. Thus the drops in voltage levels due to sudden load variations are corrected instantly. The location of the series capacitor depends on the economic and technical consideration of the line.
Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.
Capacitor banks consist of small units connected in series, parallel, or both to get the desired voltage and Var rating. When the fault or overload occurs the large current will flow across the series capacitor of the line. Thus, the excessive voltage drop occurs across the transmission line.
