A technique for estimating locations of shunt faults on distribution lines

Accurate estimation of the locations of line faults has been a subject of interest to electric power utility engineers and researchers for over twenty-five years. Almost all the research done so far has been aimed at finding the locations of transmission line faults. Lately, the location of faults on distribution lines has started receiving some attention because of public pressure on the utilities for improving the reliability of power supply. This paper presents the overview of a technique that estimates the location of a distribution line shunt fault. Some test results are also reported.
