Finding Fault: Northern Ireland Electricity tests fault repair equipment on its low-voltage underground cable network

摘要

The age profile of low-voltage cable within the Northern Ireland Electricity network ranges from the late 1930s to present day, and the cable type consists of a mixture of paper-insulated lead-sheathed cables and various forms of polyvinyl chloride-insulated cable. Some of the utility's oldest assets are located in provincial towns and cities where recent development work has provided an opportunity for urban renewal. In the event of a fault or emergency situation, the ongoing priority of Northern Ireland Electricity (NIE) - the distribution network operator for Northern Ireland - is to restore its customers' supply within a short time frame, safely and within financial and regulatory limits.
