The XDP II is a portable device for, online, factory and laboratory partial discharge measurement on electrical apparatus, or components. The XDP II can be used in accordance to IEC 60270. It records partial discharge measurements for computer analysis and diagnostic using the optional XDP II software for a PC. Using the appropriate accessories, the XDP II can be used in several applications.
Partial discharge testing is a PREDICTIVE qualitative analysis tool that can warn of a potential upcoming system failure. The XDP II is a powerful and flexible Partial Discharge Measurement System. The XDP II is an ultra-wide-band amplification system allowing to measure PD activity. It uses a very high speed detection technique to detect PD activities.
The XDP II displays graphically PD wave form and the built-in speaker allows to listen PD activities. Those information can be recorded in the XDPII along with date and time of the reading. The recorded measurements remain stored in memory even when the XDP II is shut off. This allows the transfer of these recordings to a computer upon return from the worksite.
The XDP II when used with a low noise HV source, HF capacitive coupler and other accessories provide you with a cost effective and powerful PD test system for your MV/HV network components such as transformers, switchgears, arresters, etc.
Capacitive spatula or inductive sensors used with the XDP II allow PD diagnostics and analysis on cable accessories (joints, elbows, T elbows, terminations, etc.). Those sensors detect the electric or magnetic field generated by PD.
Bi-phase coupler used with the XDP II on switchgears uses the capacitive voltage dividers of the VPIS to detect internal high frequencies of by PD.
