Product Description
VLF AC Hipot Testers Very Low Frequency HIPOTS Udey Test Kits

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.

In addition, DC proof or hipot testing has been found to be ineffective in detecting even serious defects in cables. Since this is the main objective of any hipot test, and due to the negative side effects of DC, VLF wave form testing is now recommended by almost all cable testing standards/guides such as IEEE, CENELEC, VDE, SABS etc.Acceptance or maintenance hipot/proof testing using VLF high voltage sinusoidal AC allows the operator to efficiently detect serious cable insulation defects, before they result in an in-service failure, without affecting those healthy sections of the cable that still have remaining service life.
