Power and Water rolls out fault prediction trial

Power and Water rolls out fault prediction trial

Northern Territory’s Power and Water Corporation will run a trial to anticipate and locate faults on overhead powerlines in rural areas of Darwin, which will help to improve supply reliability. 

The distribution fault anticipation (DFA) project, which saw six DFA devices installed on feeders in Darwin’s rural area, was shortlisted for Energy Networks Australia’s Innovation Award in early September. 

 Power and Water Chief Executive, Michael Thomson, said, “We are extremely proud to have been recognised as innovators among our industry peers across Australia.

“This project challenged conventional beliefs of fault behaviour and feeder performance, particularly the view that wildlife-related outages in the dry season are sporadic and transient.

“Power and Water is always looking to improve the way we do things to enrich the future of Territorians by providing safe and reliable electricity supply.”

The preliminary trial results and modelling has helped Power and Water accurately identify the location and likely cause of power outages leading to improved responses as well as plan for future investment.

The DFA devices were installed on the Dundee feeder, which has more than 200km of overhead powerlines spanning native bushland, farmland and mangrove swamps.

The trial, a first for an Australian utility, was conducted in partnership with LORD Consulting.

“Until we conducted the trial, up to 40 per cent of power supply outages in the area were due to unknown causes,” Mr Thomson said.

“The information we have will help us get power back to our customers more quickly while also ensuring the reliability of our network.

“It has also given us the confidence to consider implementing this on other feeders in the wider Darwin rural network and in the regions.”

Power and Water has more than 30 overhead feeders in Darwin’s rural area.
