DESCRIPTION : The b2 electronics PDTD68 is a
portable VLF partial discharge (PD) and Tan Delta (TD) diagnostics system designed for medium-voltage cable
testing in combination with b2 HVA VLF test sets.

The PDTD68 combines the coupling capacitor, filter and data-acquisition functions in one housing, allowing
simultaneous PD and TD diagnostics with a straightforward field setup.

Key features:
– Maximum voltage level of 68 kV peak
– Simultaneous Partial Discharge and Tan Delta diagnostics
– Designed for medium-voltage cables including XLPE, PILC and other insulated cable systems
– Precise real-time PD fault localisation
– PD localisation accuracy of 1% with resolution of 0.1 pC and 0.1 m
– Suitable for cable lengths up to 100 km
– Fibre-optic communication for galvanic isolation and interference-resistant data transfer
– Integration with b2 Suite software for measurement control, analysis and reporting
– Designed for use with HVA VLF test sets

Manufacturer-documented compliance for the PDTD68 includes IEC 60270 for test setup and calibration and IEEE
400.2 for Tan Delta testing.
