MSJF-3002B partial discharge tester (wireless WIFI version), can be used in operating high-voltage switchgear, ring main unit, voltage/current transformers, transformers (including dry-type transformers) GIS、 Insulation status detection and evaluation of overhead lines, cables and other equipment. It integrates five commonly used sensors: ultrasonic waves, ground waves, contact ultrasonic waves, ultra-high frequency and high-frequency transformers. Flexible switching of various sensors can be achieved through instructions.
◇ Product Features
Configure different sensors to realize partial discharge detection of almost all high-voltage electrical equipment;
Provide various discharge spectra such as time-domain waveform, PRPD, PRPS, etc., to achieve analysis of different discharge types;
The additional infrared thermal imaging device can convert the infrared radiation on the surface of an object that is not visible to the human eye into a visible image. Infrared thermal imaging is not affected by visible light and has advantages such as non-contact temperature measurement, smoke and fog penetration, making it very suitable for temperature detection of electrical equipment.
