摘要： An electronic fuse (506, 507) suitable for use in a direct current, DC, applications which is exposed to surges. The electronic fuse (506,507) comprises a current sensor (500) for measuring a current flowing in a current path of the DC system, the electronic fuse comprising a first transistor switch (501) which is arranged in the current path, the first transistor switch comprising at least one parasitic diode (511) having a forward direction which is opposite to an operational DC direction of the current path. The electronic fuse further comprising a controller (502) operatively connected to the current sensor (500) and adapted to control the first transistor switch (501) based on the measured current, and a current restrictor (503,520) which is capable of blocking a current from flowing in the current path in a direction opposite to the operational DC direction.

摘要： A victim unit (310, 410) connectable to a surge protective device (300, 400a) via an alternating current system or a direct current system, the victim unit (310) comprises at least one victim unit sensor (313a, 314a, 315) adapted to measure at least one status parameter at the victim unit (310, 410) and a controller (312) operatively connected to the at least one victim unit sensor (313a, 314a, 315). The controller (312) is capable of initiating a voltage limitation of the victim unit (310) by controlling the surge protective device (300, 400a) if one or more of the at least one status parameters indicates that the victim unit (310) has reached a critical state.
