Abstract: An electric power distribution switchgear (11) is connected between an electric power grid and an electric power equipment (12). The switchgear comprises (i) a synchronized vacuum switching apparatus (16) configured to break the current to the electric power equipment (12) using a synchronized technique to avoid re-ignition during the breaking and thus any transients caused by such re-ignition; and (ii) a surge arrester arrangement (17) connected to the electric power equipment (12), the surge arrester arrangement being designed and configured to only handle transients caused by the current chopping at the breaking. Hereby, the surge arrester arrangement (17) can be arranged remote from the electric power equipment (12), such as e.g. in the same casing (21) as the synchronized vacuum switching apparatus (16).

Abstract: A passive electronic fuse for protecting a DC application in the event of a fault includes a first leg including a first winding of a mutual inductor and a switch device connected in series, a second leg including a second winding of the mutual inductor. The first leg and the second leg are connected in parallel and a self-inductance of the second winding is lower than a self-inductance of the first winding. The second leg further includes a capacitor connected in series with the second winding of the mutual inductor, and the switch device is a thyristor or a switch device with switching properties of a thyristor.

Abstract: In a protective arrangement of at least one switchgear (SWG 1 , SWG 2 ) comprising a link (BB 1 , BB 2 ) interconnecting at least a first and a second feeder (F 3 ) being power transmission elements provided with corresponding circuit breakers (CB 1 , CB 2 , CB 3 ), the protective arrangement comprises a current limiting device (12), an earthing switch (ES 1 ) and a control unit. Upon fault detection on one power transmission elements (F 3 ) and current limiting device activation, where the fault causes a fault current to run through the circuit breaker (CB 3 ) of the faulty power transmission element (F 3 ) of which a part passes through the current limiting device (12), the control unit monitors the current limiting device operation, determines if the operation is non-satisfactory and closes the first earthing switch (ES 1 ) in case it is, thereby lowering the current through the circuit breaker (CB 3 ) of the faulty power transmission element (F 3 ) to a level where this circuit breaker (CB 3 ) may be opened.

Abstract: A system for transient over voltage protection of a three-phase transformer. Two surge arresters are series connected across each winding of the transformer and the center point connection of the two surge arresters is electrically connected to a middle location of the winding. Three additional surge arresters are electrically connected from each phase to ground in the case of either a delta or Y connected transformer; and/or connected from a neutral point to ground in the case of a Y connected transformer. The system allows for all of the surge arresters to be packaged as an integrated surge arrester system to minimize induced transient over voltages and high stresses on the transformer winding due to internal resonances.
