Patent attributes
In order to improve an electrical supply network for on-board electrical systems of vehicles, comprising at least one network system with a current feed-in connection, with at least one load connection and with a supply line system which is guided from the current feed-in connection to the at least one load connection and has at least one current-carrying line harness and at least one protective casing surrounding this, in such a manner that an electric arc can either be avoided or when an electric arc is formed this can be terminated again as quickly as possible, it is suggested that the supply line system be provided with a detector line system which is connected at a first end to a detector circuit and is connected at at least one additional end to an end element, that the detector circuit generate a test signal which is influenced in the defect-free state by the detector line system and the end element and that the detector circuit detect a defect due to deviation of the test signal from a reference value range corresponding to the defect-free state.
