HV Diagnostics HVA-60 Electrical Plant Tester
 

Description
It is well known that DC testing of aged extruded cable such as XLPE and EPR is potentially damaging to the cable insulation causing 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. It is because of these limitations that International and National bodies such as CENELEC, VDE, SABS and the IEEE now recommend testing utilising low frequency AC test systems. VLF testing enables the cable test engineer to detect insulation defects before the cable fails in service.
