Portable GIS detector using partial discharge UHF detection technology, supports up to four detection channels, can according to different requirements can choose to access multiple UHF sensor unit, a detection signal through conditioning, signal acquisition, amplification detection pretreatment processing after the transmission to the monitoring computer. Insulation condition assessment of GIS, and gives a reasonable warning information, provide a strong basis for condition based maintenance decision of GIS equipment.

Main functions and features:

1, UHF sensor technology, to avoid the low frequency noise interference andimproves the signal to noise ratio;

2, four channel simultaneous acquisition of partial discharge signal, setting the disturbance channel according to the scene, the scene of the ultra high frequencyinterference suppression;

3, single detection and continuous detection of two kinds of operation mode, the PRPD and the PRPS two kind of display mode, can display more than 50 power frequency signal detection

4, frequency domain analysis, FIR filter, pulse extraction and other signal processing method;

The program contains the data statistics and analysis of the 5 fingerprint database,software, automatic analysis of the defect type;

6, to support continuous monitoring mode, can be on the historical analysis of signal processing, diagnosis suggested a believable.
