  • What is Hipot Testing What is it Used For?

    Mar 25, 2019 · Hipot testers can measure from 5k volts to 400k volts, depending on the size of the tester. The duration of the test should directly relate to safety standards issued for the device. Normally, it should be one minute for products covered by IEC 60950, the international standard for rated voltage.

  • Should I use a high-pot or a megohmmeter? - Megger

    In contrast, a high-pot uses higher voltages and currents, and while it can provide a measurement, its primary function is to identify and kill the weak; like taking marginal equipment out of service by breaking down weak insulation before a costly malfunction occurs on the job. Testing can be performed in DC or AC voltage.

  • The Hi-pot Test - In Compliance Magazine

    Oct 15, 2014 · Answer: In the old days, the traditional value for the hi-pot test was 900 volts. Gradually, this increased to 1000 volts. And then, the familiar formula, 2V + 1000, gave us 1250 volts for a 125-volt rating. There are many papers published on studies of overvoltages in household and commercial power distribution circuits.
