摘要：
The invention relates to an arrangement (10) for ground fault monitoring of an AC circuit between, on one hand, a neutral conductor (N′) of the AC circuit and, on the other hand, a protective ground wire (PE) or a ground wire with a series connection of ohmic resistors (R1, R2, R3), which has a first terminal (101) for the neutral conductor (N′) and a second terminal (102) for the protective ground wire (PE) or ground wire, wherein the arrangement includes at least one means for detecting a break of one of the resistors (R1, R2, R3) of the series connection.
