MSJF-3002B, Partial Discharge Tester

Partial discharge tester/detector (wireless WIFI version) can be used for insulation status detection and evaluation of operating 

high-voltage switchgear, ring main units, voltage/current transformers, transformers (including dry-type transformers), GIS, overhead

 lines, cables, and other equipment.

It integrates five commonly used sensors: ultrasonic, ground wave, contact ultrasonic, high-frequency, and high-frequency

 transformers. Flexible switching between sensors can be achieved via commands.

◇ Product Features

Configured with different sensors, it can detect partial discharge in almost all high-voltage electrical equipment;

It provides various discharge spectra such as time-domain waveforms, PRPD, and PRPS, enabling analysis of different discharge types;

The added infrared thermal imager can convert the infrared radiation invisible to the naked eye from the surface of an object into 

a visible image. Infrared thermal imaging is unaffected by visible light, offering advantages such as non-contact temperature 

measurement and smoke/fog penetration, making it ideal for temperature detection of electrical equipment.
