Transitional processes at switching-off capacitor banks by circuit-breakers with pre-insertion resistors

Transitional processes of switching-off high-voltage capacitor banks by circuit-breakers with pre-insertion resistors are considered in the paper. Capacitor banks switching-off process by circuit-breakers with PIR was studied from the point of view improving electromagnetic environment via reducing switching currents by pre-insertion resistors. It is shown in the paper that appropriate resistances and pre-insertion times provides both reducing switching currents and stable operation of resistor.
