摘要

A protective device for a transformer (4) which is connected on the high-voltage side by means of supply lines (2) to a network (12) for the transmission and distribution of electrical energy, wherein the transformer (4) has a neutral grounding (13), wherein each supply line (2) is connected to ground (11) by means of a grounding transformer (1), wherein the grounding transformer (1) has a neutral point resistance (R0GIC) which is lower than the neutral point resistance (R0sub) of the neutral grounding (13), such that Geomagnetically Induced Current (GIC) flowing on the supply lines (2) is diverted to ground (11).
