Cable Diagnostic Tools
For non-destructive diagnostic testing to determine the quality of a cable’s insulation with minimal risk of failure, HVI recommends tan delta and partial discharge testing for valuable diagnostic data about cable insulation integrity. Both use a VLF source to perform elevated voltage, off-line testing. Tan delta testing measures insulation health, while PD identifies specific problem areas and assesses their severity.
