摘要

A protective device for a transformer (4) which is connectedon the high-voltage side by means of supply lines (2) to anetwork (12) for the transmission and distribution ofelectrical energy, wherein the transformer (4) has a neutralgrounding (13), wherein each supply line (2) is connected toground (11) by means of a grounding transformer (1), whereinthe 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 GeomagneticallyInduced Current (GIC) flowing on the supply lines (2) isdiverted to ground (11).
