Abstract: A medium voltage switching device includes an electromagnetic actuation chain and a power supply which provides electric power to the electromagnetic actuation chain. The power supply includes at least a first power supply device which is electrically connected to a medium voltage power distribution line, so as to drain electric power directly from the distribution line, and a second circuit configured to store at least the electric energy drained from the medium voltage power distribution line, and to thereby provide the electromagnetic actuation chain with electric power.

Abstract: A device for controlling the opening/closing operation of an electric switchgear in a power disribution network comprising a control unit, for controlling an electromagnetic actuator operatively connected to the movable contact of said switchgear. Said control unit includes first processing means for generating, based on predefined data, a first control signal which is indicative of the actual law of motion of said movable contact of the switchgear.
