Overvoltage Protection of Series Capacitor Banks
Series capacitor banks consist mainly of the capacitors as well as their protection system and function to increase power flow on an existing system by reducing line impedance. Their first application dates back to 1928 when GE installed such a bank – rated 1.2 MVar – at the Ballston Spa Substation on the 33 kV grid of New York Power and Light.

6.1.2: Capacitance and Capacitors
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as ...

Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
