Abstract
The motion of electrons in c-C4F8 and N2 gas mixtures for a pulsed Townsend discharge is simulated by the Monte Carlo method. The effective ionization coefficient, , over the E/N range from 160 to 480 Td is calculated by employing a set of cross sections available in the literature. From the variation curve of with the C4F8 mixture ratio k, the limiting field of the gas mixture at different gas content is determined. The required gas pressure ratios comparable with the insulation property of SF6 and GWP at this gas pressure were also investigated. It is found that the insulation characteristics of the N2 and c-C4F8 gas mixtures are comparable with the N2 and SF6 mixture, but the GWP of the former is significantly lower than that of the latter. Simulation results show excellent agreement with experimental data available in the literature.
