Data sheet

Overview

The PD90-2 and PDTD90-2 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. With PDTD90-2 - VLF testing, PD diagnostics and TD diagnostics can be carried out simultaneously, saving time and avoiding preconditioning of the cable, which would lead to false results.

Performance

PDTD90-2 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

PDTD90-2 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 HVA90/4 device (not in scope of supply), PDTD90-2 creates a full-featured and full-value system for 90 kV output voltage scope.

Compliance

PD90-2 and PDTD90-2 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.
