Fault location

This chapter discusses the challenges of distribution system fault location and presents possible algorithms to overcome some of the challenges. One type of fault location method assumes the fault type to be known and the other dispenses with fault type information. Fault location methods for a single fault and methods for simultaneous multiple faults are presented. When there are only limited measurements available, a portion or portions of the network may be unobservable in terms of fault location. More meters will be needed, and design of an optimal meter placement scheme is possible based on network topology and parameters. It is noted that a great deal of valuable literature on fault location has been published in the past. Interested readers are suggested to read more on this intriguing topic.
