Dielectric strength is defined as the maximum voltage required to produce a dielectric breakdown through the material and is expressed as Volts per unit thickness. Additional requirements for tests using direct voltage. Send us a request Need help or have a question? A higher dielectric strength represents a better quality of insulator.
Additional requirements for tests using direct voltage Status: Each of these three methods has the same basic set-up, which consists of the test specimen placed between two electrodes in air or oil. There are three basic procedures that can be used to determine the dielectric strength of an insulator.
