The Power Line Fault Locating System is a means of locating faults in a utility power system by sampling the noise at multiple positions around the system and correlating and summing the resulting data. When the processed data produces a spike, a noise source has been detected. The position of the spike in the data will indicate the location of the noise source with great precision. With three of more receivers the location of the fault can be determined in two dimensions. The invention can operate on both continuous noise resulting from minor flaws in the power system as well as the noise burst resulting from a power system failure. Noise resulting from minor flaws may come from slack line fittings, electrical leakage in insulators or at poles. A burst of noise may come from insulator flash over, lightning strike, or something contacting a power line.
