PTI-G2 GIS insulation status monitoring system is applicable to real-time monitoring of 10KV and above GIS and on-site analysis and diagnosis of partial discharge. Combining digital signal processing technology and virtual instrument technology, the system can display the amplitude and frequency of partial discharge in GIS at each monitoring point in real time, determine the relative position of the discharge source, and give an alarm if necessary. It can also store the test spectrogram, analyze the discharge type and discharge trend, so as to timely find the insulation defects in GIS, provide criteria for evaluating its insulation level and aging degree, and provide basis for the maintenance of high-voltage GIS. The transformer partial discharge online monitoring system detects the internal discharge signal of the transformer and diagnoses the insulation state of the transformer.
