Eric,
Getting "zapped" during a hipot test would mean test setups improvements
and/or additional safety precautions are needed quickly. Having such a
problem may have serious consequences if they are not resolved quickly.
Since you're not sure of the mechanism as yet and have not provided any
real details, I can only hypothecate generally of some some possible
scenarios, which are:
1) Insufficient training of test personnel and/or documentation
This can produce a host of problems from incorrect test setup to leaning
on
the EUT during testing. This is one test that only trained personnel be
allowed to operate due to the hazardous nature of the test.
2) Defective test equipment and/or EUT
3) Incorrectly connected test setup and/or EUT
Either can produce potentially hazardous situations.
The operator of this test must be either adequately instructed against or
physically prevented from contacting the test setup and EUT during this
test.
Actually, I believe the only way to get "zapped" during a hipot test is to
come into contact with the hipot test voltage (assuming that the operator
is getting zapped from the test voltage iteslf).
Good luck in finding the corrective measure to this problem and I would
behove you to find it quickly.
Anyway, this is just my 2 cents worth.
Regards,
Ron Pickard

We're looking into a problem where, on occasion, our manufacturing
operators are getting zapped while operating a production HiPot test
station. (Just how this happens is yet to be determined.) I've reviewed
literature on HiPot equipment, but nothing I have suggests any operator
safety features are available. I can imagine some simple methods to
prevent this, but I thought it might be worth soliciting ideas from those
that have successfully solved this particular problem, since it may be a
more common problem than most of us realize.
