Manufacturers of infrared cameras are now making low-cost solutions of adequate image quality that work great for infrared programs just getting started. This technology is capable of finding both electrical and mechanical defects, and it is very easy to understand and accept.
- Electrical defects – Most defects in electrical apparatus create localized heating, which is easily detected with an infrared camera. Problems with electrical apparatus are almost always due to loose and/or dirty connections.
- Mechanical defects – Defects like misalignment, v-belt and sheave problems, bearing defects, and lubrication problems all produce heat within the components. This heat is easily detected by the infrared camera.
Note: Infrared thermography is not the most preferred method for detecting mechanical defects, as the defect is already significantly down the defect progression path before the localized heating begins to occur.
