PD60-2 & PDTD60-2
Partial Discharge diagnostics systems

The PD60-2 and PDTD60-2 offer both portable and built-in solutions for diagnostics of medium voltage cables, rotating machines and transformers. Diagnostics of medium and high voltage cables provides the opportunity for early detection of vulnerabilities and preventative maintenance work to be carried out before the cable fails in service.

Performance: PDTD60-2 includes integrated Tan Delta diagnostics capabilities and thus features simultaneous comprehensive PD and TD diagnostics, saving time and avoiding preconditioning of the cable, which would lead to false results.

Comprehensive diagnostics: PDTD60-2 allows measurement of cables with different lengths at constant frequency, being a prerequisite for the comparison of PD and TD results from previous measurements.

Application: Suitable for testing XLPE, PE, EPR and PILC cables up to 100 km.

PD localization: Precise localization of PD faults in cables with the accuracy 1% and resolution 0.1 pC per 0.1 m.

Complete system: In combination with the HVA60 device (not in scope of supply), PDTD60-2 creates a full-featured and full-value system for 60 kV output voltage scope.

Compliance: PD60-2 and PDTD60-2 devices are in compliance with guides like IEEE 400.2 and 400.3 and standards HD 620, CEI EN 50393, IEC 60270, IEC 60502-2 and their local derivations.

Characteristics

Simultaneous PD and TD measurement (b2 Suite version 2.0 and higher)

PDTD60-2:
The parallel measurement of PD and TD results in significant time savings. In addition, it prevents negative influence on the results of a second test carried out due to feeding high test voltages during the first test.

True modularity

All our high voltage cable test sets can be easily extended to any HVA test set, with corresponding voltage range, to a complete diagnostics system. This keeps the initial investment low.

Automatic mode

With the corresponding b2 Suite software (mandatory for PD test sets), you get manual and incremental test modes with self-explanatory menus, as well as a fully automatic measurement mode reducing operation efforts.

POWERFUL DATABASE

The convenient search function of the comprehensive b2 Suite database allows fast comparisons with past PD measurements and performing reproducible measurements.
