The complete inspection of power facilities includes IR thermal imaging camera, UV imaging camera and visible light detection. Now we can analyze the specific differences between IR thermal imaging camera and UV imaging camera.

The IR thermal imaging camera uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image. This thermal image corresponds to the heat distribution field on the surface of the object.

The UV imaging camera uses a special instrument to receive the ultraviolet signal generated by the object's discharge. After processing and imaging, it can determine the position and intensity of the object's corona.

(1) The spectral range of IR thermal imaging camera is 8-14um. The spectral range of UV imaging camera is 0.25-0.28um.

(2) In power applications, IR thermal imaging cameras are generally used to monitor temperature changes caused by overheating and poor connection caused by high resistance, which are generally related to current. Uv imaging cameras are generally used for wIRe damage and separator slack in power applications. The detection of corona and arc is generally related to voltage.

Ultraviolet imaging technology can effectively and intuitively observe the discharge of high-voltage equipment, providing a new and powerful diagnostic method for live detection. IR thermal imaging camera technology can monitor the surface temperature changes of objects in real time, which is useful for early detection of hidden dangers in power supply equipment. That's why UV imaging camera technology and IR thermal imaging camera technology have irreplaceable advantages, and they are complementary.
