According to the latest international and domestic technological progress, we have developed NAJFD-3000 series partial discharge detection system successful.
 
Characteristics of the product:
1, Pure process control mode for partial discharge detecting system 
2, English menu display
3, Automatic calibration, automatic synchronization, automatic voltage recording, automatically measuring and playback & saved 
4, Automatic generating test report
5, 2D and 3D partial discharge display 
6, Adopting digital window technology, with strong anti-interference.
7, Dual-channel measurement and differential digital technology, which can measure the partial discharge signals of two sample or a sample with two points, can easily analyze the source of  partial discharge signal.
