How does a hipot tester work
WebThe hipot test is used to determine whether the ground wall can handle an over-voltage situation. An over-voltage is a voltage higher than the peak operating (line-to-line) voltage of the device under test (DUT). Standard peak voltage is 1.41 x RMS voltage. Hipot tests are used for everything from very low voltage devices to high voltage equipment.

Did you know?
WebThe hipot test, derived from the term High Potential Test, is a direct application of a high voltage to a unit under test. The test voltage is usually much higher than the usual operating voltage in order to stress the dielectric properties of the device under test. The test is designed to detect that gaps or clearances between conductive parts ... WebTo allow a hipot test insert and turn the key to the "Ready to Hipot" state. To work in a test area, turn the key to the "Disable Hipot" state, pull the key, and carry the key with you. Key switches are a good way to limit testing to only trained personnel. Palm Switches. To allow a hipot test an operator must use each hand to hold down a button.
WebTraditionally DC hipot testing was used for field testing of cables, but DC testing has been shown to be ineffective for withstand testing of modern cables with polymer based insulation (XLPE, EPR). DC testing has also been shown to reduce the remaining life of cables with aged polymer insulation. [1] Web5.3 The test specimen shall be placed between the con-tacts of the HiPot test equipment (see Figure 1). Start the HiPot sequence. 5.4 Upon completion of the test, the HiPot sequence should include the discharge of the test specimen. (Safety note: Larger test specimens, with high capacitance density, may take more time than expected to discharge.)
