Abstract
This paper deals with how to select the rated voltage and insulation level for the high-voltage shunt capacitor. It is pointed out that the rated voltage should be selected according to the practical operating voltage and short-circuit capacity of the power network
and also according to the capacity of the capacitor bank and reactance ratio of the series reactor. The insulation level should be selected according to the way of capacitor bank connection and whether the metal case is grounded or not. It is indicated that correct selection of the rated voltage and insulation level is of great importance to safe
fault-free operation of the high-voltage shunt capacitor in the power network.
