Abstract:
A circuit breaking arrangement is disclosed, which is adapted to be coupled to a transmission line arranged to carry direct current for controllably effecting discontinuation of flow of direct current in the transmission line. The circuit breaking arrangement includes a current interrupter unit adapted to, when actuated, interrupt current in the transmission line and a first resonance circuit and at least a second resonance circuit. Each of the first and the at least a second resonance circuit is adapted to, upon actuation of the current interrupter unit and when the respective resonance circuit is activated, generate a resonance current superposing current of any arc generated in the current interrupter unit after actuation thereof. At least during a predefined period immediately after actuation of the current interrupter unit a resonance current that has been generated by the first resonance circuit flows into the current interrupter unit from a different direction than a resonance current generated by the second resonance circuit would have, or vice versa.
