(3) Service life of capacitor

Opening and closing of the capacitor produces sever conditions for contactors,

such as high frequency inrush current and interpole recovery voltage more than

twice the normal voltage.

The criteria of the maximum number of the capacitor current switching operations

is shown in the graph below. The vacuum interrupter should be replaced when the

number of switching operations in the graph is reached.
