Summary on Grant Application Form |

Faults on high voltage power systems plant result in the flow of substantial current. During arcing faults, the non-linearities of the arc produce a spectrum of frequencies which can extend into the MHz region. If the fault current has a significant vertical component, such as an earth fault on an overhead line tower, then the tower will act as a radio frequency transmitter and will result in the emission of an atmospheric radio wave a sferic - which can propagate to considerable distance at the speed of light. Due to recent developments in timing technology, it is now feasible to consider a system for mapping arcing faults by detecting and timing the arrival of sferics in a network of geographical dispersed receiving outstations; from this information the fault position may be inferred. Such a system would be able to map faults over a large geographical area, and not be restricted to a defined circuit as is the case for conventional fault locating equipment.
