Summary
Documents
UKPN identified opportunities to improve the detection and location of intermittent faults on LV underground cables.
This project combined the use of an intermittent cable fault location device (T-P22) with an improved re-energisation device (REZAP Fault Master) so that LV intermittent faults can be better managed and customer interruptions reduced.
Objectives
The project has developed the following techniques:
- Time reflection to determine fault location
- Transient impedance fault location
- Travelling wave fault location
- An auto reclosing device.
