Hipot testing
Hipot testing
(OP)
We want to use hipot test in slip rings (24 rings) and we've made an automatic tester which uses switching matrix and a hipot tester.
We would like to know if anyone of you knows or is aware of the minimum dwell time for applying 250 V on this test? The matrix switches the tester to do the hipot between one circuit (ring-cable) and the rest, then another circuit and the rest, and so on.
Thanks.

Perhaps UL could offer you some guidance as well.

A good web-site that had a lot of technical articles on product safety testing is www.asresearch.com.
Good Luck

RE: Hipot testing
In fact, the electrical tester we use is from AS Research and the test runs under a production basis which is a strong factor for the timing of the test as a normal one consists of continuity, hipot and insulation resistance and it takes about 130 seconds per piece from the time the operator takes the piece to test until he releases it.
All this becomes an issue engineering-vs-production because as engineers time up the tester, off course, less pieces can be tested in an hour. That's why we're looking for a point were we won't sacrifice the pieces with a strong test and test as many pieces as we can per hour.
Thanks again.
