Testing the time characteristics of high-voltage switch closing, opening, and contactor suction, release time, bounce, synchronization, and mechanical life operation of the contactor. It is suitable for testing the characteristics of high-voltage switches (or double coil independent opening and closing self locking contactors and air switches) with independent closing and opening coils (with locking mechanisms), as well as for testing the characteristics of contactors with only a single coil (electrically holding, without locking mechanisms) for opening and closing.
