HV Diagnostics HVA60 60kV VLF/DC test set

Click2Contact

The portable HV Diagnostics HVA60 60kV VLF/DC test set provides real-time data of actual output waveform. Available to rent from TechRentals, the product is suitable for testing and commissioning electrical plant equipment including cables XLPE, PE, EPR, PILC, capacitors, switchgear, transformers, rotating machines, insulators and bushings. All test results are stored on an on-volatile memory for downloading to a PC for review and analysis.

DC testing of aged, extruded cables such as XLPE and EPR is potentially damaging due to premature failure of the cable under service conditions. Any form of DC testing has been found to be ineffective in detecting even serious faults in such cables. VLF testing is a preferable alternative as it enables the cable test engineer to detect insulation defects before the cable fails in service.

Features include true sine wave low-frequency output; 1 µF (approximately 3000 m of cable) testing at 0.1 Hz and 60 kV peak; fully automatic or manual cable test sequences; and compliance with international standards/guides such as IEEE 400.2, VDE 0296 and CENELEC.
