Product details
Product IntroductionProduct Introduction
Ultrasonic partial discharge detector is used for transformers, reactors, generators, transformers, bushings, etc. of various voltage levels and capacities GIS、 Power cables, power capacitors CVT、 Partial discharge live circuit testing of lightning arresters, high-voltage switches, switchgear, and other AC/DC high-voltage electrical equipment.
When partial discharge occurs, physical phenomena such as ultrasonic waves, heat, light, and magnetism are generated, among which ultrasonic waves propagate in the form of spherical waves around the sound source. The HTJF-9002 ultrasonic partial discharge detector uses the signal generated by receiving ultrasonic waves from partial discharge to determine the presence and location of partial discharge, and combines real-time displayed images and data to quickly diagnose the condition of partial discharge. This tester integrates two detection methods: transient to ground voltage and ultrasonic.
Product nickname: Partial Discharge Tester, Ultrasonic Partial Discharge Tester, Partial Discharge Tester, Partial Discharge Tester, Partial Discharge Tester
