Review of Temperature Measurement Technology With Infrared Thermal Imager

In order to ensure the continuous and stable operation of power system, the infrared detection technology is introduced. The technology uses infrared thermal imager and other temperature measuring instruments to evaluate the operation state of electrical equipment based on the thermal distribution of equipment. It is one of the most important methods of energized test at present. Infrared detection principle, the application of infrared thermal imager in power system and the influence factors of infrared detection are introduced. Combined with calibration situation of infrared thermal imager in the past two years in a certain area, the necessity of infrared thermal imager calibration is analyzed, to provide reference for the correct use and maintenance of infrared thermal imager.
