Unlike low voltage testing that simply makes sure your cables function, high voltage testing will make sure your cable is safe.
High voltage, or hipot, testing checks for good isolation in your cable. During a hipot test, the tester will ensure that no current is flowing where there should be no current. Current may be escaping through defects in the cable such as:
- Nicked or crushed insulation
- Stray wire stands or braided shielding
- Conductive or corrosive contaminants around the conductors
- Terminal spacing problems
- Tolerance errors in IDC cables
High voltage testing may not be necessary for all your cables, but it can help make your cables safer by finding flaws.
