What is a high voltage shunt capacitor?

High voltage shunt capacitors are used on electric power networks at transmission and distribution levels. Capacitor banks are found at substations for power factor (PF) correction and voltage control. Shunt capacitors, properly sized and located, provide voltage regulation.

What are high voltage shunt capacitor banks (SCB)?

Abstract— High voltage shunt capacitor banks (SCB) are widely used on power systems. The installation of shunt capacitor banks has beneficial effects such as the voltage regulation and the reduction of the losses of active power to be transmitted.

Are shunt capacitor banks beneficial?

The installation of shunt capacitor banks has beneficial effects such as the voltage regulation and the reduction of the losses of active power to be transmitted. At the same time, the presence of shunt capacitor banks impose constraints on apparatus present in a substation [1,2].

What is the insulation level of a shunt capacitor bank?

F. Insulation level of the shunt capacitor bank neutral Since the shunt capacitor bank is ungrounded the neutral should be fully insulated. In this case and for a 230kV system the basic impulse insulation level (BIL) of the neutral should be of 950 kV.

Do shunt capacitor banks exist in a substation?

At the same time, the presence of shunt capacitor banks impose constraints on apparatus present in a substation [1,2]. Currently, no specific configuration of shunt capacitor bank is recommended, grounded and ungrounded shunt capacitor banks can exist on the same transmission system.

What is the function of fuses in shunt capacitor banks?

The function of fuses for protection of the shunt capacitor elements and their location, external or internal to the capacitor unit is part of the design of shunt capacitor banks. The capacitor units for capacitor banks without fuses are the same as externally fused units.
