Basics of Infrared Scanning

E.H. Emery Electric Ltd. Truck

The most common failure mode for electrical equipment is due to build up of heat at loose, corroded, or overloaded electrical connections. Infrared scanning was developed to detect these flaws before they lead to a catastrophic situation.

Infrared cameras convert the invisible heat radiated by failing electrical equipment into visible light images. This technology allows equipment to be assessed while in service (on-line), eliminating the need for disruptive power outages. The ability to detect radiated heat also allows inspection of electrical connections that are not easy to access by other means.
