Abstract

equation over the density-normalized electric field strength, E/N from 0.1 to 1000 Td
(1Td=10-17 V.cm2). The swarm parameters such as, drift velocity, electron mean energy,
characteristic energy, ionization and attachment coefficients were analyzed using a set of
cross sections for the gases. The density-reduced effective ionization coefficient (α − η)/N
has also been calculated.The present results agree well with previous experimental and
theoretical results. Moreover, the E/N value at which ionization coefficient equals
attachment coefficient, the critical field strength was calculated to be (E/N)cr=199 Td for
pure N2O gas, which is lower than that of pure SF6 gas (361 Td), a widely used as
insulating gas. In addition, it’s found that the critical field strength (voltage breakdown)
increase with increasing SF6 concentration in the gas mixtures.
