Partial discharge(PD) is a pulsed discharge that produces a series of physical phenomena and chemical changes such as light, sound, electrical and mechanical vibrations in and around electrical equipment. When insulation defects occur in high-voltage electrical equipment, partial discharge signals will be generated. Through the detection and analysis of these signals, it can be judged whether there are hidden dangers of insulation inside the high-voltage electrical equipment, and the further expansion of potential accidents can be prevented. So regular PD testing is critical as part of a condition-based management (CBM) regime. This enables operators to obtain baseline PD readings to assess insulation quality, locate PD activity and determine maintenance goals



GTPD-92 partial discharge detector developed by our company is a multi-functional hand-held instrument. It is based on TEV, ultrasonic, UHF and high-frequency current(HFCT) detection methods to test the partial discharge of the HV equipment, and can read the partial discharge amplitude and spectrum. The waveform can provide storage and readout functions of two-dimensional and three-dimensional maps, etc., and can better evaluate the partial discharge of electrical equipment. partial discharge detector is suitable for partial discharge detection of electrical equipment such as GIS, switch cabinets, transformers and power cables. The equipment is portable and easy to operate, and all detections do not have any impact on the operation of high-voltage equipment. The product can observe the measurement signal in multiple cycles, identify the frequency of discharge, and analyze it through various modes, which can clearly determine the fault.

The partial discharge detector adopts a brand-new design and uses the currently popular Android system, which is easier to operate and use. In addition, it integrates 5 million pixel cameras to take pictures to facilitate inspection records; RFID is conducive to expanding the application of the Internet of things; internal integration discharge type library is provided to facilitate the comparison and verification of discharge conditions.
