A novel method of locating overhead line faults, by triangulating the location of the fault using a set of receivers.
What is the project about?
The project is about a novel method of locating transient arcing faults on overhead line networks, which aims to improve the way we locate and repair faults.
How we’re doing it
This is a two-year collaborative project with Scottish Power Energy Networks, the EIC and Elimpus. In the first year, the aim is to test, build and demonstrate a set of receivers that can recognise the signal produced by an arcing fault, and using the time of difference of arrivals at each receiver, triangulate the geographical location of the fault. Once the first set is built, the aim is to build several more so that we can deploy them onto our respective networks for our field staff to trial over the second year.
What makes it innovative
This method is innovative because the predominant method of locating faults is via fault passage indicators, which show a direction in which a fault came from, which may not have much efficacy in locating a fault in a highly branched network. This approach is innovative in the sense that it gives the geographical location of the fault, removing the need to send out linesman teams for line patrols and instead head straight to where the fault was detected.
