ABSTRACT:
A synthetic test circuit for testing a metal-encapsulated high voltage circuit breaker of a type which is grounded on one side and which includes several switching gaps arranged in series. The testing circuit includes a high voltage source and a high current source for stressing the switching gaps during testing and, in addition, a high voltage means for applying a high voltage to the encapsulation simultaneously with the application thereto of a further voltage from the high voltage source. The high voltage is chosen to be of opposite polarity to the further voltage and the encapsulation is insulated from ground potential during application thereof.
