Working Principle of ultraviolet camera

Ultraviolet imaging technology for electric discharge detection is to use a special instrument to receive the signal generated by corona discharge. After processing, it is imaged and superimposed with visible light image to achieve the purpose of determining the position and intensity of corona, and provide a basis for status detection of electrical equipment. The wavelength range of ultraviolet light is 10nm ~ 400nm. The sun also contains ultraviolet light, but since the earth's ozone layer absorbs some wavelength components, the solar ultraviolet spectrum radiated to the ground is actually above 300nm, and the wavelength region below 300nm is called the solar-blind zone. Most of the ultraviolet rays generated by the discharge of high-voltage equipment are in the range of 280nm~400nm, and a small part of the wavelength is in the range of 230nm~280nm. This part of the wavelength of ultraviolet light can be used as a basis for judging equipment failure.
