WebGround bond testing requires application of a high current source to a conductive surface of the product and measurement of the voltage drop across the ground connection. This is … A dielectric voltage withstand test (also known as a hipot test) is done by applying a voltage higher than operating voltage to the device or installation under test. In this test, the electric insulation of a product or installation is put under a voltage stress much higher than its normal operating voltage. If the hipot test is done for type testing purposes, a much larger voltage may be applied.
