Case Study: Fault Prevention With A DNO

The Service That Could Have Saved A DNO $300,000.

The UK has fourteen Distribution Network Operators (DNOs) based on the historic utility regions that existed before privatisation in the early 1990s. They are responsible for providing and maintaining the electricity infrastructure (cables, towers, meters) that allows the generation companies and private electricity providers to deliver power to homes and businesses.

A DNO was concerned that of one of its substations was at risk because of its riverside location. The DNO requested the installation of EA Technology’s UltraTEV® Monitor to perform a long-term soak test to pick up any irregularities between routine services. The most vulnerable assets were identified and we installed the system in November 2014.
