Hipot testing is an abbreviation for high potential (high voltage) testing. Hipot testing is a test to check the dielectric strength of a product, in which a high voltage is applied to confirm that no current flows, no breakdown occurs, and good insulation is maintained.

Matsusada Precision manufactures and sells high voltage power supplies used in insulation resistance tests such as Hipot testing.
