  • Determining location of faults in power transmission lines
    Patent number: 4499417
    Abstract: The position of a fault occurring in an electric power transmission line (1) is determined by "labelling" a voltage or current pulse originating from the fault and reflected by the end of the line, or some other point in the system, moving back towards the fault, and then measuring the time taken for the labelled pulse to return to the measuring point near the end of line. The "labelling" is achieved by predicting from known data and the time of arrival of the reflected pulse the amplitude of the voltage pulse and comparing the prediction with the measured value. Apparatus for carrying out the method is described.
