# Series Shunt Capacitor

**Where W is the Wattmeter reading.**

**Series shunt capacitor**.
Series shunt compensation and FACTs Devices.
Shunt capacitors are an integral part of a power system because it helps in power factor correction.
Series Compensation Series compensation is basically a powerful tool to improve the performance of EHV lines.

It is always better to use a shunt capacitor C with series inductor L to form an LC Filter. Assume the feeder is balanced and has a series impedance of 05 j1 Ωmile. This capacitor reactance is usually used for the system through static capacitors either in series or shunt connection with the system.

Advantages of Series Compensation 1. During conduction the capacitor starts charging and stores energy in the form of the electrostatic field. The net result is improvement in power factor.

Only inductor is used. Only capacitor is used. At C 12 µF and at L 015 H.

Calculation of series and shunt capacitance are done in the same method. As the functionality of the capacitor allows current to take the lead of voltage levels capacitor reactance might be utilized to revoke the systems inductive reactance. The unfused arrangement would typically be utilized on units below 345 kV where a series chain of capacitor units are not practical.
