Product Description

portable offline partial discharge monitor for GIS, cable test

I.Product overview
Portable partial discharge detector is a special instrument for measuring and analyzing insulation performance of power equipment. it is one off-line partial discharge detector.
This system adopts modern electronic and computer integrated technology, realize signal(analog, electronics, digital) amplification , filtering, data acquisition, data processing, graphic display, and automatic test report generation, so as to complete the partial discharge measurement and analysis.
This instrument is easy to carry, and with fast measurement, strong anti-interference ability, which is easy to use on site. Its configuration software is with functions such as time-domain graphics, 2D, 3D statistic map, alarm history, history largest, pulse counting. The software can also enquire and analyse a phase waveform in detail and the window can be zoomed in and out at will. It can also analyze the spectrum of the data, analyze the spectral content of the discharge waveform, make the discharge waveform more comparable, and comprehensively analyze the test data to reduce the influence of the non-stability factors on the test results.Automatic or manual record are used to keep test data and transient discharge waveform which can provide reference for later data analysis.
