Central Networks, the electricity distribution company for central England, is launching its yearly eye-in-the-sky helicopter patrols across the county next week as part of its work 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 to 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 those "hot spots" for repair works.

Jim O'Sullivan, Director of Infrastructure Services at Central Networks, said: "Using a helicopter is the easiest and fastest way to carry out checks on large sections of the network.

"We're responsible for around 750 primary and grid substations across central England and this is vital work. It helps us spot potential problems before they develop and that means we can plan our investment and maintenance work more effectively.

"Once we get the information back from the helicopter we can make sure we can get out there and do the necessary work before it begins to cause problems for our customers."
