PDXW-701 Multifunctional Partial Discharge Tester
About the product
Partial discharge is a type of pulsed discharge that generates a series of physical phenomena such as light, sound, electricity, and mechanical vibrations inside and around electrical equipment. These various physical and chemical changes accompanied by partial discharge can provide detection signals for monitoring the internal insulation status of electrical equipment. When insulation defects occur in electrical equipment, there will be the generation of partial discharge signals. By detecting and analyzing partial discharge signals, it is possible to determine whether there are insulation hazards inside and further expand the prevention of potential accidents.
This instrument is a multifunctional live detection support instrument, which is based on detection methods such as TEV,AE,UHF,and HFCT to test the partial discharge situation of electrical equipment. It provides partial discharge amplitude, PRPS, PRPD, continuous, fly, pulse, phase, waveform, and other graphs, which can effectively evaluate the partial discharge situation of electrical equipment. Suitable for live partial discharge detection of electrical equipment such as transformers, reactors, GIS, switchgear, high-voltage cables, overhead lines, etc.
