High voltage withstand test
In electrical engineering, a dielectric withstand test (or pressure test, high potential or hipot test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground. The test is a means to qualify a device's ability to operate safely during rated el… Webspecified voltage. Note that this test is to check for ability to withstand a specified voltage and not to determine the break-down value. 5.4.2 Test to Breakdown, Short-time Test The voltage shall be increased from zero to breakdown at a uniform rate. The rate of rise shall be 0.5 or 1.0 kilovolts per second. depending on the total test time ...
