  • Broken conductor detection method and apparatus
    Patent number: 10365313
    Abstract: A broken conductor detection method and apparatus are disclosed. In one embodiment, the apparatus includes a measurement module to measure, at a node of a distribution system, a voltage value of each distribution feeder of the distribution system; a check module to check whether the measured voltage value of each distribution feeder is less than a voltage threshold used for the distribution feeder, the voltage threshold used for the distribution feeder being calculated based on a mean value of measured voltage values of other distribution feeders in the distribution system; a generating module to, upon a checking result indicating that a measured voltage value of a distribution feeder of the distribution system is less than the voltage threshold used for the distribution feeder, generate a signal indicating that the distribution feeder of the distribution system has a broken conductor; and a sending module to send the generated signal.
