Dielectric Strength Testers
These specialized high-voltage power supplies are designed especially for measuring dielectric strength or breakdown as required by many CSA and UL specifications for both qualifications and production testing.
The Dielectric Strength Test consists in measuring the current leak of a device under test, while phase and neutral are short circuited together. The measure result of a Dielectric Strength Test is a current value, which has to be lower than the indicated limit from the international standards.
A Dielectric Strength Tester (also called hipot tester, dielectric strength tester, flash tester, high voltage tester) is then used to measure this current.
