Web10 apr. 2024 · This is also called dielectric strength. It is measured in kV/mm or V/mm or kV/cm. It means that if the voltage exceeds the dielectric strength then the dielectric would rupture and the tightly bound electron could come loose and a huge correct will flow in the dielectric. Air is a very bad conductor of electricity and has high dielectric ... In SI, the unit of dielectric strength is volts per meter (V/m). It is also common to see related units such as volts per centimeter (V/cm), megavolts per meter (MV/m), and so on. In United States customary units, dielectric strength is often specified in volts per mil (a mil is 1/1000 inch).
