Electric supply system including short-circuit and interrupt detection for vehicle power systems

The arrangement has at least one network system (10) with a current feed connector (14), at least one load connector (16) and a supply line system (12) with at least one current-carrying line (20) and at least one enclosing protective covering. The supply line system has a detection line system (24) connected to a detector circuit (30) at one end and to a terminating element (32) at one or more further ends. The detector circuit detects a fault if a test signal deviates from a desired value range.
