摘要：Several new approaches to locating ground faults for ungrounded and Peterson Coil grounded systems. The system approach couples information from a relay located at a substation and remote ground-fault detectors to indicate the fault phase. The system uses a diagnostic signal generator that operates at a distinct frequency other than the power-line frequency which provides a circuit path and signal to help to locate ground faults. A diagnosis signal injection method for fault location is also developed.
