Electrical thermography is a preventive suvey of electrical switchboards in particular, but is also beneficial for troubleshooting other components such as electric motors, transformers and charging stations.
Electrical thermography is a contact-free measurement of temperature difference. The survey takes place using an infrared (thermally sensitive) camera which measures temperature differences in the electrical components and electrical installations.

Please refer to this example.


 If this temperature differencehad not been discovered, it could have caused a breakdown.
