The dielectric rigidity of a certain material is a limit value of the applied voltage on the material thickness (kV/mm), and with this minimum value, the atoms which compound this material ionize themselves and the dielectric material leaves to work as an insulator. Factors that influence in the dielectric rigidity value:

• Temperature;
• Thickness of the dielectric material;
• Application duration of the Potential Difference;
  Increasing rate of voltage;
• For a gas, the pressure is an important factor.

*** capacity of the equipment: 60 kV

Applications:

Determination of the dielectric rigidity and the voltage applied, by insulating liquids or in air, in plates for production of insulating materials.
