Abstract:
1. Electrical supply network for on-board electrical systems of vehicles, comprising: at least one network system with a current feed-in connection; at least one load connection; and a supply line system leading from the current feed-in connection to the at least one load connection, said supply line system having at least one current-carrying line harness and at least one protective shielding surrounding the line harness; the supply line system being provided with a detector line system connected at a first end to a detector circuit and connected at at least one additional end to an end element, the detector line system comprising a line system which is separate from the current-carrying line harness, the detector circuit generating a test signal influenced in a defect-free state by the detector line system and the end element, and the detector circuit detecting a defect in the supply line system due to deviation of the test signal from a reference value range corresponding to the defect-free state.
