JFD-2010 Dual-Channel Digital PD Detector 

   JFD-2010 Dual-Channel Digital PD Detectorfeatures high sensitivity and wide test specimen applicability.It is a new-generation PD detector with Chinese characteristics reaching international advanced levels,Suitable for PD quantitative testing of motors, transformers, instrument transformers, cables, bushings, capacitors and other HV equipment。.

Structure:

1、 Independent dual-channel digital PD measurement，synchronous sampling, processing, display；

2、Internal/external sync freely selectable, with zero marking and phase resolution；

3、  Display mode: freely selectable ellipse, line, sine wave modes；

4、Single PD pulse waveform analysis to determine discharge characteristics；

5、Save test data/waveforms anytime, re-display and analyze previously saved records；

6、Gain Range: independent per-channel adjustment, waveform display smoothly adjustable without affecting results；

7、Single capture of special/random waveforms for detailed analysis；

8、Anti-static interference, removes phase-fixed interference signals；
