A dielectric is a substance in which an electric field may be maintained with zero or near-zero power dissipation. A dielectric material is an electrical insulator. In a dielectric, electrons are bound to atoms and molecules; hence there are few free electrons. The dielectric strength of a material is an intrinsic property of the bulk material and is not dependent on the configuration of the material or the electrodes with which the field is applied. In a given configuration of dielectric material and electrodes, the minimum electric field that produces breakdown. At breakdown, the electric field frees bound electrons, turning the material into a conductor.

The dielectric strength is normally expressed in volt/mm; the voltage at which the insulator breaks down, divided by the thickness in millimeters.

Measuring the dielectric strength of a material, for example paper, includes the following: (Source: Buckleys URVAL, Ltd.)

The standard dielectric strength for paper is tested to be 16 MV/m.
