Damage to offline flyback by hipot test

Flyback

Well-Known Member
Hi,
What kind of damage will be done to an offline flyback during repeated testing at 4kvrms with hipot tester?
The test from L+N to output.

Last sentence of this says hipot testing can damage equipment...


"Excessive voltage levels or extended test durations can increase the risk of insulation breakdown, equipment damage, or electrical accidents."

Well any of the isolation components could fail. I would assume that the likely suspects are the transformer insulation, the opto-isolators and any capacitors that connect the HV side to the LV side.
