Protective device for a power supply system, method for the protection of a power supply network and high-voltage - a battery power supply.

摘要

The present invention relates to a signaling of a detected fault arc within a power supply network, by feeding a high-frequency signaling in the power supply network. In this way, the fed-in high-frequency signalling by the supply lines of the power supply network are transmitted. In this way, the signaling for a detected fault arc be reliably transmitted, and a risk due to an interruption of an additional line can be eliminated.
