Question

What does dielectric strength mean?

Answer 1

1. The dielectric strength can be defined as the electrical strength of the insulating material.
2. In a strong electric field, the insulator breaks down allowing the flow of charge.
3. The dielectric strength of insulating material is defined as the maximum electric field that it can sustain without undergoing dielectric breakdown and becoming electrically conductive.
4. Dielectric strength can also be stated as the maximum voltage needed to cause a dielectric breakdown in an electrically insulating material.
5. The dielectric strength can be measured in volts per unit thickness.
6. The higher the value of dielectric strength more electrically insulating is the material.
7. The dielectric strength is applied in the development of materials for energy storage applications.
8. It is used in capacitors also.
