Calculation of discharge inception voltages in argon+SF6 mixtures

In this study discharge inception voltages in Ar+SF₆ binary mixtures are calculated based on the streamer criterion when the gas mixture is subjected to electrostatic fields. The calculations are done for different contents of SF₆ in the mixture and the total gas pressure is varied as a parameter from 50 kPa to 200 kPa. The computed discharge inception voltages from the streamer criterion appear to compare well with our experimental data and our limiting fields for Ar+SF₆ mixtures calculated from the basic data using Monte Carlo simulation
