Partial Discharge Inception Voltage By Insulation Thickness

This calculator provides values of the voltage that can be applied in an insulation system comprising of insulation and an air-gap. You can change the insulation thickness and/or the relative permittivity as well as the environmental conditions. 

The calculator can be used for altitudes between 0m and 20,000m. However, the voltages calculated are generally conservative (i.e. overly safe) at lower pressures.
