Drift-diffusion modelling of breakdown of SF6 mixtures

The SF6-N2 mixtures show increasing breakdown voltage with increasing pressure and the greatest increase in breakdown strength occurring for lower SF6 content (0% - 30%) while SF6-CO2 mixtures, show the greatest increase in breakdown strength at higher SF6 content (>50%). Experimental testing of the synergy effects of the SF6-N2/CO2 mixtures

Dielectric Coatings for High Voltage Gas Insulated

It seems that there is an optimal concentration of oxygen for N2/O2 mixtures which is 40% at 0.5 MPa gas pressure. The LI breakdown strength of SF6/N2 gas mixtures is also evaluated in [19]. Figure 2.3 shows the comparison of the LI breakdown strength of air and SF6/N2 gas mixtures. Negative lightning impulse voltage is applied in the breakdown
