Digital partical discharge detector Features  With anti-interference mode, which is unique in China, so that to attenuate space interference from site test.  Great anti-shock ability.  Digital PD detector with great accuracy (class 5, the highest accuracy in China)  Data collection card with high-speed and great capacity, can collect PD data continuously, has good data reproducibility and high accuracy. Test function,  Analyze function (multi-parameter analysis, 2 dimensional atlas analysis and 3 dimensional atlas analysis );  Data save function;  Report generation & printing function.  This device displays PD waveform (ellipse,sine wave and straight line ), PD value and testing voltage simultaneously.  Auto gain adjustment during calibration and testing process, which is easy to operate without manual operation  Apply to power supply of 50Hz, 150Hz and up to 400hHz. And it can trace frequency phase of testing power supply.  Open door and time window can be set arbitrarily, down to 1degree.  Small size and low weight.
