Abstract: A high voltage direct current interrupting arrangement consists of two electrical switches connected in series. One of the switching devices is a commutating circuit breaker which is connected in parallel with a series connection of a capacitor and a spark gap. A surge diverter is also connected in parallel with the commutating circuit breaker. The surge diverter takes over the current and breaks it during a breaking operation whereafter the other switching device is opened to isolate the circuit.

Abstract: A high voltage switching device is operated by a compressed gas valve having an electrodynamic operating means. The operating means comprises a stationary coil which is inductively connected to a short-circuit winding supported by the movable member of said valve. To operate the switching device a capacitor located at high potential is connected to said coil through a photoelectric switching member.
