Analysis and comparison of fault location systems in AC power networks

Summary

Rapid and precise location of line faults is becoming more important in modern AC power systems. Different methods of fault locating, each requiring very different levels of investment, were reported to this working group from 40 utilities around the world. They ranged from simple, low-cost solutions to more expensive, sophisticated systems utilizing multiple techniques to improve performance. Each fault locating technique has its own advantages and disadvantages when applied to different power network topologies. For utilities to implement an appropriate fault locating system, it is important to have good knowledge of the different established techniques and their application to different power network topologies. This technical brochure explores commonly implemented fault locating techniques and presents practical aspects to those implementations in different applications.
