Q: What does “AC Hipot Test" mean?

A: AC hipot, or AC withstand voltage testing, applies a specified AC voltage to evaluate the insulation withstand capability of electrical equipment.

Q: What is the difference between an AC resonant tester and a conventional AC hipot tester?

A: The resonant system uses resonance to reduce the reactive power demand of capacitive test objects, making it especially suitable for large-capacitance equipment such as long cables and GIS.
