Abstract

This paper deals with a 300kV dc charging system to be used ?s a voltage source in a circuit breaker synthetic short-circuit-test facility. Cockcroft-walton circuit is used to step up the rectified voltage from a single phase transformer of which primary winding is hooked up to an ac220 wall plug. Two systems with the same ratings have been designed and manufactured. The two system have been made of different supporting structure with different insulating materials. The paper describes a couple of charging schemes, system configurations and the synthetic test circuit in which the developed system is to be used.
