Voltage withstand testing is done with a high- voltage source and voltage and current meters. A single instrument called a "pressure test set" or "hipot tester" is often used to perform this test. Hipot Test is short name of high potential (high voltage) Test and it is also known as Dielectric Withstand Test. Continuity. The withstand voltage test also called the dielectric strength test or hi-pot test, is a test to evaluate whether the insulation of electrical products and parts has sufficient dielectric strength against the voltage. A higher-than-normal voltage is applied to the insulation for a specified period. ents), and the electrical equipment, formed by the internal connections and by the incoming and outgoing termina is regard, there has been an evolution which has resulted in the replacement of the previous Standard IEC 60439 with the present Stand rd IEC 61439. 11 of IEC 61439-1 outlines two critical tests to assess a switchgear panel's ability to withstand short circuit stresses: Icw Test – Tests the busbar system's ability to endure the mechanical forces generated during a fault. The test may be between mutually insulated sections of.
