Abstract (en)
A short-circuiting device (14) comprises a triggering circuit (16), an actuating element (30), a stationary electrode (20) and a moveable electrode (22), where the actuating element (30) is moveable between a first retracted position and a first extended position and joined to the moveable electrode (22) for being moved between a corresponding second retracted position, where there is gap of a first distance between the moveable and stationary electrodes (22, 20), and a second extended position, where the gap has a second lower distance, the triggering circuit (16) being configured to trigger a current to start to flow between the electrodes (20, 22) after the actuating element (30) has been actuated to move from the first retracted position and before reaching the first extended position and the current continues to flow in the gap after a first zero crossing and at least until a second zero-crossing.
