ProTenetIntl™ Partial Discharge Monitor PTI-P3
PTI-P3 transformer partial discharge online monitoring system detects the internal discharge signal of the transformer and diagnoses the insulation state of the transformer.
Combined with digital signal processing technology and virtual instrument technology, it can display the amplitude and frequency of partial discharge inside the transformer 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 internal insulation defects, provide criteria for evaluating the insulation level and aging degree, and provide basis for its maintenance work.
