  • Faulted phase decision method between current and voltage based delta phase selectors
    Patent number: 8045307
    Abstract: A method of identifying fault conditions in a three phase power system includes monitoring the changes of both the current and voltage properties on a three phase power network. A maximum phase change value of both the current and voltage is determined. Either the voltage or the current values are selected, whichever includes the largest maximum phase change. Thereafter, the selected set of measurements is analyzed to determine whether a fault condition exists on any phase of the three phase power.
