Ground faults from positive conductors on fixed structures with relatively high ground resistance are a persistent problem in DC feeding systems. Such faults are difficult to detect because of the weakness of the fault current. In turn, if these faults continue for several seconds, they can lead to broken overhead contact lines, feeder wires or masts. A new system was therefore devised to detect ground faults using a protective wire and 'protection devices.' This paper presents the system outline and the results of several indoor and on-site experiments on the proposed system.
