Abstract

The invention relates to a circuit assembly () for fault detection in an ungrounded high-voltage system () having a connected inverter () and having at least one resistor () between a high-voltage potential () of the high-voltage system () and a reference potential (), the circuit assembly () comprising: a sensing circuit (), which is designed to tap a voltage from the resistor (), to generate a first measurement value therefrom and to provide the first measurement value at an output (); and an evaluation device (), which is connected to the output () of the sensing circuit (), the evaluation device () being designed to compare the first measurement value with a first limit value and to output a first signal if the first measurement value exceeds the first limit value.
