Abstract: In a high voltage circuit breaker of low liquid type the breaking chambers are pressurized to prevent the circuit breaker from restriking when breaking capacitive loads. All the seals required for these pressurized chambers are located below the liquid level in each chamber.

Abstract: An arrangement for preventing high voltage liquid minimum circuit breakers from restriking when breaking capacitive loans. The liquid in the breaking chambers is put under high pressure by supplying compressed gas through an insulating conduit from earth potential to a space above the liquid level in each chamber. Between the gas-filled space and the conduit is a valve, which is open during normal operation but closes during a breaking operation, thus preventing carbonized liquid from penetrating into the conduit.
