Switch arcing

SpletThe invention relates to a metal enclosed circuit breaker (1) comprising a first arcing contact (2) and a second arcing contact (3), whereby the first arcing contact (2) and/or the second arcing contact (3) is axially movable along a switching axis (4), thereby forming, during a breaking operation, an arc (5) between the first arcing contact (2) and the … Splet19. dec. 2024 · switches are not intended to actively switch load current. In the above clip, the arcingis due to the attempted interruption of comparatively low reactive (capacitive or "charging") currents drawn by the open transmission line. Even with reduced current, the disconnect switch was not always capable of opening the circuit. At
