Overview

b2 electronic Diagnostics System PDTD120-2 (combined with VLF generator) provides a pure sinusoidal output voltage with stable frequencies. This is a pre-condition of direct comparison of PD and TD diagnostics results across cables of different lengths. The characteristics at ever-changing frequencies and varying output voltage waveforms provide no basis for reliable comparisons. Pure sinusoidal output voltage is recommended by standards (such as IEEE400.2-2013) and therefore clear guidelines and test procedures are provided. With PDTD120-2 - 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

PDTD120-2 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

PDTD120-2 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 Localisation

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

Complete system

In combination with the HVA120 device (not in scope of supply), PDTD120-2 creates a full-featured and full-value system for 120 kV output voltage scope.

Compliance

PD120-2 and PDTD120-2 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.
