Publication number: 20240118330Abstract: 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.Type: ApplicationFiled: October 4, 2022Publication date: April 11, 2024Applicant: Schweitzer Engineering Laboratories, Inc.Inventors: Arun Shrestha, Sathish Kumar Mutha, Brian A.
