The project looks to improve the accuracy of low voltage fault location techniques, reducing repair times and shortening outages for our customers. Firstly, a range of acoustic devices and fault passage indicators (FPIs) will be trialled on a test network. The most successful devices will be passed on to the field teams for trialling.
This project will establish the technical and commercial viability of a selection of acoustic cable fault location devices and fault passage indicators that can work in conjunction with existing proven LV fault location technologies. It will also look to maximise the portfolio of technologies available for LV fault location and make recommendations for optimal adoption of the suitable devices for business as usual use. Environmentally, being able to more accurately pinpoint an underground cable fault reduces the number of excavations and volume of spoil.
