NDB XDP-II Expert Partial Discharge Detector
 
The NDB XDP-II Partial Discharge Testing Kit is a portable, battery-operated partial discharge (PD) detector designed for both online and offline condition assessment of medium- and high-voltage electrical assets. It supports advanced PD detection and analysis for applications including power transformers, metal-clad switchgear, cable accessories, overhead assets, insulators, arresters, and cable terminations and switches. When combined with a pico-coulomb calibrator and PD coupler, the XDP-II performs offline PD testing with pC measurements, making it a versatile solution for field, laboratory, and substation environments.
