What is Thermography?

Infrared Thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometres or 9–14 µm) and produce images of that radiation, called thermo-grams. Since infrared radiation is emitted by all objects above absolute zero according to the black body radiation law, Thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, Thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night. As a result, Thermography is particularly useful to military and other users of surveillance cameras.

When electrical energy flows in an electrical circuit there is conversion from electrical energy to thermal energy. As resistance to the flow of electrical energy increase, surface temperature of component increases as well as a result additional infrared energy is emitted from the surface of the object & the infrared camera detects this deviation. What Should one look for in Electrical System Substation Equipment like Transformers, Circuit breaker, CT / PT / Isolators, Capacitor Bank, lighting arrestors, Transmission line, Distribution Panels, Switch gears

• The use of electronic “cameras” to detect radiant energy or heat
• Produces a visual image called a thermogram (or heat picture)
• Some cameras infer temperature based on the amount of radiation detected
• Thermography is a powerful tool for machine and building maintenance
