Expert partial discharge detector

The well-established XDP-II™ is a battery-operated portable device allowing partial discharge detection and analysis. The data is saved in its internal memory for local or further analysis on the PC-based XDP-SOFT™. Paired with the proper accessories, the XDP-II™ becomes a powerful solution for many applications such as Cable Joints and Elbows, Switchgear, Offline, Acoustic, TEV, Rotating machines, Transformer, etc…
