GDUVI-41 Partial Discharge UV Imager
GDUVI-41 UV imager adopts ergonomic design and key operation, which is very suitable for daily maintenance of various high-voltage electrical equipment. The instrument adopts solar-blind technology to simultaneously image the visible light and ultraviolet light paths, and realizes the location of the ultraviolet light-emitting position through the real-time synchronous fusion of the two images, which can be detected around the clock. The video display can display the ultraviolet video and the visible light video separately, or the superimposed composite video, which can count the ultraviolet light spots in the selected range and provide the measurement data.
The instrument is small, light, powerful, and has good controllability. It can help you find and eliminate equipment failures in advance and prevent accidents. It is the most ideal common preventive maintenance testing tool in various industries such as power, electrical, railway, and factories.
