WebbFailed Hipot - "Over Current" Heating the connectors in a cable with a heat gun might make these problems go away, only for them to return within 24 hours. *Note Cables that have "leakage" failures may test OK with an ohmmeter even though they fail on your tester. Two possible reasons: Cirris testers test one wire against all others tied together. Webb25 aug. 2015 · As I noted before we had power supplies with isolation transformer (SMPS) that caused HIPOT failure by merely connecting the secondary isolated ground to primary ground, resulting in more capacitive load to the primary side and more stress on other components on the primary side with breakdown across transformer isolation as a …
