Estimation of Fault Location on Distribution Feeders using PQ Monitoring Data

Abstract

This paper investigates the challenges in the extraction of fault data (fault current magnitude and type) for fault location application based on actual field data and proposes a procedure for practical implementation. The proposed scheme is implemented as a stand-alone software program, and is tested using actual field data collected at distribution substations and the results are compared with results of the state-of-the-art software package currently used in a utility.
