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.

GDHX-8300F Wireless Phase Detector
GDHX-8300F Wireless Phase Detector is mainly used for phase sequence identification and labeling of power transmission and distribution lines.
Its working principle is: the phased base station regularly collects the phase signal of a certain area line as a standard signal and uploads it to the main station server. During measurement, the sensor collects the measured line signal and sends it to the handheld device. The handheld device applies to the server for the data of the phasing base station at the same time. By comparing the two phase data, the true phase of the measured line can be calculated.
The complete set of equipment mainly consists of the main station server, phasing station, handheld machine, sensors and accessories.
