Features
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
accuracy.
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.
