The dielectric strength of air is about 3 kV/mm. This means that air can withstand a certain amount of voltage before it breaks down and conducts electricity. In electrical equipment, a higher dielectric strength of air allows for higher voltages to be used without causing electrical breakdown or short circuits. This helps in ensuring the safe and efficient operation of the equipment.

What happens to Dielectric strength when heated?

When a dielectric material is heated, its dielectric strength typically decreases. This is because heat can modify the material's properties, structure, and ability to resist electric fields. As a result, the material may become more conductive and less effective at insulating against electrical charges.
