Applications of Thermography:

Electrical engineering applications:

• We know that the electrical energy can be dissipated in the form of heat. Therefore the heat emitted can be detected using thermography technique.

• Some connections (or) joints produce heat; therefore thermography camera can be used to focus the hot spots in electrical panels and wirings. Here the heated components appear as bright spots on Thermograms.

• In the case of 3-phase connections, sometimes the current may not have equal magnitude, then there exists a temperature difference between the phases. This can be detected using thermographic cameras.

• It is very useful in finding the faults in transformers, overhead electrical connections, etc from the ground itself.

Medical applications:

• It is used to find the heat emitted from human body for diagnostic purposes.

• DITI technique is used in screening breast cancer, vascular disease etc., by detecting abnormal heat emitted from the particular part of the body.

General applications:

• It is used to find the heat loss around windows, door frames, buildings etc.,

• It is used to detect the roof problems (or) defects (due to rain water trapping)

• It is used for detecting the poor bonding, cracking, voids etc.,

• It is used in refineries, power plant boilers, gas leakage detection, furnace refratories.

• It is used to find the faults in IC’s.
