Electricity distribution company Central Networks will begin helicopter patrols this week to inspect some of its 750 primary substations across the Midlands.

A helicopter fitted with thermal imaging equipment will be used to spot potential hazards and identify where future work may be needed in electricity substations across the region.

The specialist cameras show a glowing bright light when there are high levels of heat between connections, joints or any other positions, allowing engineers to prioritise repair works at ‘hot spots’.

Central Networks’ Director of Infrastructure Services, Jim O’Sullivan, said: “The thermal imaging patrols help us carry out essential work by spotting potential problems before they develop and affect the electricity supply to our many customers.

“Using a helicopter is the fastest and safest way to carry out these checks across large sections of our network and also allow us to plan our maintenance work more effectively.
