  • FAULT LOCATION ESTIMATION USING INCREMENTAL QUANTITIES
    Publication number: 20240118330
    Abstract: A method and a system are used to analyze incremental quantities. The electrical measurements associated with a loop in a multiple-phase electric power delivery system are obtained before a fault occurred on the loop and after the fault occurred on the loop, and differences between the electrical measurements are used to determine incremental quantities. The incremental quantities are used to determine a location of the fault on the loop. Multiple loops in the multiple-phase electric power delivery system may be monitored to determine corresponding fault locations on each loop.

  • Fault location during pole-open condition
    Patent number: 11346878
    Abstract: The present disclosure illustrates the errors that are encountered when using both single-ended and double-ended normal-mode fault location calculations when a fault occurs in a pole-open condition. The disclosure provides systems and methods for accurately calculating the location of faults that occur during pole-open conditions, including single-ended approaches and double-ended approaches.
