London Electricity has installed a distributed temperature sensing (DTS) system using fibre optics technology from York Sensors to monitor power cables in a 10km stretch of underground tunnel in South West London.

It will enable the company to maximise efficiency of a new distribution network, ensuring customers’ demands are met safely.

The first phase of a £52 million refurbishment programme, which involves the installation of 132kV circuits linking Wimbledon, Wandsworth and Pimlico, features York’s long range DTS 800 system.

The DTS system works by linking fibre optic cable to an opto-electronic processing unit and optional PC. Continuously updated temperature readings are provided every two metres over a 15km range.

It is supplied with DTS Manager, a Windows-based package displaying temperature profiles and alarms. Temperature measurements are accessed via modems, and the system can in fact be interrogated from any fixed or mobile location.
