Learn the differences between dielectric strength testing and hipot testing, their applications, IEC standards, and how to choose the right electrical safety test.
Using a hipot tester’s leakage readout as a substitute for a proper leakage current measurement is like checking your tyre pressure with a nail gun. It will tell you something, but not the right thing. Hipot leakage is measured at overvoltage through potentially compromised insulation; touch current is measured at rated voltage through an intact, operating product. The numbers are not comparable, and a certification body will not pretend otherwise.
It was supposed to be an ordinary afternoon. A woman in Kerala pulled into a public charging bay, topped up her EV, and reached to unplug the connector.
Working with high voltages requires a proper setting up and operating a hipot testing workstation.
For manufacturers in industries like Consumer Electronics, Power Supply and Inverters – making the right decision about HiPot testers is non-negotiable as it has a direct bearing on product safety and compliance.
‘Hipot’ is short for ‘high potential,’ which interestingly again is short for the more technical term, ‘Dielectric Withstand Test‘. It’s an electric safety test, where a direct application of a high voltage is made to a unit/device to test the effectiveness of its insulation. The test voltage is usually much higher than the operating voltage […]
