Impulse withstand

WitrynaFor impulse tests, impulse voltage of the prescribed magnitude as per specifications is applied, and the cable has to withstand five applications without any damage. Usually, after the impulse test, the power frequency dielectric power factor test is done to ensure that no failure occurred during the impulse test. Partial Discharges: WitrynaWithstand voltage testers must be able to apply the test voltages described in the standard and to measure the breaking current. They are also subject to requirements such as the following as imposed by standards and laws: • The voltmeter precision must be JIS Class 1.5 or greater.
