Description
Overview
GAOTek transformer PD tester is a multi-functional handheld instrument. It is based on the detection methods of ground wave, ultrasonic, UHF and high-frequency current to test the partial discharge of the equipment, read the partial discharge amplitude and spectrum waveform, and provide the storage and readout functions of two-dimensional and three-dimensional maps, it can better evaluate the partial discharge of electrical equipment. This Partial Discharge Detector is suitable for local discharge detection of GIS, switch cabinet, transformer, power cable and other electrical equipment. The partial discharge test equipment is portable and easy to operate. All tests will not have any impact on the operation of high-voltage equipment. The product can observe the measured signal for multiple periods, identify the discharge frequency, and analyze it through multiple modes, so as to clearly judge the fault. This partial is convenient for inspection and recording; RFID is conducive to expanding the application of the Internet of things; A discharge type library is integrated inside to facilitate the comparison and verification of discharge conditions.
