  • Fault region location system
    Patent number: 8315827
    Abstract: A method for identifying an approximate fault location in a power transmission line comprises detecting first and second dominant frequencies in first and second recovering voltages resulting from the fault without using the velocity of either of the recovering voltages.
    Type: Grant
    Filed: April 20, 2009
    Date of Patent: November 20, 2012
    Assignee: Southern California Edison
    Inventors: Vitaly Faybisovich, Mark I. Khoroshev
  • Method of detecting fault extinction during a three-phase autoreclosing cycle in an AC transmission line
    Patent number: 7961445
    Abstract: A new method for three-phase reclosing of transmission lines is disclosed. According this method, after the type of fault is identified and the faulted line is opened for all three phases from both ends, fault extinction is recognized by comparison of amplitudes and angles of voltages induced at opened phases with predetermined settings. The transmission line is reclosed after the fault is found to be extinguished.

  • Multifactor adaptive auto-reclosing of high voltage transmission lines
    Patent number: 7317599
    Abstract: One embodiment of the invention provides a method, system, and device for the auto-reclosing a faulted power transmission line by measuring the characteristics of voltage on a faulted line to determine, in real-time, the moment that the secondary arc is extinguished. A device automatically selects between a plurality of arc extinguishing algorithms based on the compensation level of the transmission line. As a result, reclosing an on-going or existing fault is avoided, while restoration of normal power supply is performed with the minimal possible time interval.
