Abstract

An electricity network fault detection system comprising at least two fault detectors which detect a signal comprising a sferic caused by a fault in the network, and a system processor which receives details of the detected sferic from each of the detectors, and determines the approximate location of generation of the sferic. When a fault occurs in an electricity network, a fault current is generated. These, in conjunction with a part of the network where the fault current has occurred which acts as an antenna, produce electromagnetic radiation in the form of atmospheric radio waves or sferics. It has been realised that these sferics may be used to detect a fault and to determine its approximate location.
