Abstract
An arrangement for interrupting current comprises a first and a second terminal. First, second, and third parallel circuit branches are arranged between the terminals to electrically connect two power networks. The first parallel circuit branch comprises a mechanical main circuit breaker, the second parallel circuit branch comprises an energy absorbing device, and the third parallel circuit branch comprises a resonant circuit and a voltage control means arranged in series. The voltage control means is controllable to inject energy into the resonant circuit to force a rapid increase of alternating current, wherein the alternating current flows in a loop containing the first and the third parallel circuit branches as the mechanical main circuit breaker is controlled to open to interrupt main current. Zero cross-over of the current through the mechanical main circuit breaker is thereby realized as the alternating current amplitude exceeds the main current amplitude.
