N the Hydro-Québec transmission system, high voltage shunt capacitor banks represent more than 12000 MVAR distributed mainly over four levels of transmission system voltages : 69kV, 120kV, 230kV and 315kV. The size of individual SCB varies between 8 MVAR on the 69kV level to 384 MVAR on the 315 kV level.

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].
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.
