A method and a device for locating faults along an energy supply chain for DC current systems. To provide a reliable fault location for DC current systems, at least one reference short circuit is generated at a known reference fault location of the energy supply chain and at least one physical property of the energy supply chain is determined during the reference short circuit. At least one physical property of the energy supply chain during the operational short circuit is determined, and a fault location of the operational short circuit is determined, taking into account at least the determined physical properties during the reference short circuit and the operational short circuit and the reference fault location.
