Capacitor withstand voltage test calculation
Chapter 5 Capacitance and Dielectrics
In electrical engineering, a dielectric withstand test (or pressure test, high potential or hipot test or insulation 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 durin…
