NIA SSEPD 0023: Fault Passage Indicators for Sensitive Earth Faults (SEF)

Key activities

A technical method is proposed and it involves carrying out tests on a revised Fault Passage Indicators from Bowden Brothers which has been modified to detect Sensitive Earth Faults (SEF) faults down to 4A. The tests will be performed at the Power Networks Demonstration Centre (PNDC) in Cumbernauld to ensure that the revised device has significantly improved sensitivity over our current range of FPIs.

Expected outcomes

This project will be successful if we are able to determine the ability of the revised FPI to reduce CMLs due to SEF faults.
