Abstract
An arrangement for interrupting current comprising a first and a second terminal adapted to electrically connect two sections of a power system is provided. A voltage control means is controllable in use to inject energy into said loop to force a rapid increase of an alternating current flowing through said main branch while being controlled to open to interrupt a main current, and whereby zero cross-over of the current through the mechanical main circuit breaker is realized as the amplitude of the alternating current exceeds the amplitude of the main current. An energy absorbing device is adapted to limit the voltage across said capacitor and said mechanical breaker when the mechanical breaker is open, and across an inductive element if the voltage across the mechanical breaker breaks down, at or immediately after an opening process, thereby limiting the rate-of-rise and the peak of the current through said loop.
