I have a lot of experience with hipots and their use in the lab and on the assembly line. However, your note has no evidence to get one started. Go to the assembly line and interview the operators. Ask specifically what they were touching when they got the shock. If you let me know what you learn I can probably start you off in the correct direction. Also tell how the connection is made between the hipot and the product. Hipots vary from simple transformers to sophisticated processor controlled testers, so give me some idea of what you are using. If the hipot is a current limited tester (in the 10-30mA range) you can take a reasonable time to correct the problem. If the hipot is one that will maintain full output under a fault, I recomment that you stop the factory from using it until the situation is corrected.

Reply-To: [email protected] 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.
