Dielectric Strength

Detailed explanation-1: -Dielectric breakdown is the failure of an insulating material to prevent the flow of current under an applied electrical stress. The breakdown voltage is the voltage at which the failure occurs, and the material is no longer electrically insulating.
Detailed explanation-2: -Dielectric strength is the voltage that an insulating material can withstand before breakdown occurs. It usually depends on the thickness of the material and on the method and conditions of the test.
Detailed explanation-3: -The process by which this occurs is called dielectric breakdown. The value of electrical potential at which this occurs is called the breakdown voltage (measured in volts). The dielectric strength is the potential gradient at which this occurs (expressed in volts per meter, kV/mm, etc.).
