Abstract

A device for detecting faults in an electric line between a voltage source and a load is disclosed. The device includes a signal-generation unit a signal-receiving unit and an evaluation mechanism. The signal-generation unit is configured to produce a power-line signal and transmit the power-line signal via the electric line to an external mechanism. The signal-receiving unit is configured to receive a response signal from the external mechanism. The evaluation mechanism is configured to detect an occurrence of a fault, when the signal-receiving unit fails to receive a response signal.
