Digital partical discharge detector


² Ø With anti-interference mode, which is unique in China, so that to attenuate space interference from site test.

² Ø Great anti-shock ability.

² Ø Digital PD detector with great accuracy (class 5, the highest accuracy in China)

² Ø Data collection card with high-speed and great capacity, can collect PD data continuously, has good data reproducibility and high


Test function,

² Ø Analyze function (multi-parameter analysis, 2 dimensional atlas analysis and 3 dimensional atlas analysis );

² Ø Data save function;

² Ø Report generation & printing function.

² Ø This device displays PD waveform (ellipse,sine wave and straight line ), PD value and testing voltage simultaneously.

² Ø Auto gain adjustment during calibration and testing process, which is easy to operate without manual operation

² Ø Apply to power supply of 50Hz, 150Hz and up to 400hHz. And it can trace frequency phase of testing power supply.

² Ø Open door and time window can be set arbitrarily, down to 1degree.

² Ø Small size and low weight.
