Electrical inspections detect hot wires and fuses or blown transformers Faults such as bad connections can be detected with infrared thermography long before they become a serious problem. Early diagnosis and repair can result in thousands of dollars in savings. In Process Applications, items such as steam traps and valves can be inspected to ensure they are in proper operating condition. This trap shows steam on one side of the trap and cooler condensate on the other. Research and development can detect circuit boards under load, or stress points of tires, airbags, engines, etc.
Friction generates heat.
The flow of electricity generates heat. These simple principles allow researchers and engineers to use IR cameras to their advantage.
