Abstract
Series capacitor equipment for distribution networks has a capacitor, voltage-dependent resistors as over-voltage protective means for the capacitor, a mechanical high-speed circuit-closer and a switch connected in parallel with the high-speed circuit-closer, for bypassing the equipment. At an overcurrent in the power line, tripping members initiate closing of the high-speed circuit-closer, which closes rapidly sufficient to protect the resistors against overload, and of the switch, which relieves the high-speed circuit-closer. The high-speed circuit-closer, the switch and the tripping members are mounted in a grounded cubicle.
