Determination of Insulating Properties of SO2 gas from BOLSIG+ Calculated Swarm Transport Coefficients

In this paper, the Transport Coefficient of SO
2
gas are calculated from swarm model design using BOLSIG+ which is user-friendly open-source computer program based on numerical solution of Boltzman equation (BE) up to two-term approximations. To ensure close agreement of calculated transport coefficients for SO
2
gas with impending experimental works, first we calculate these coefficients for SF
6
, and CO
2
compared the results with reported values. Reasonable agreement is found between calculated and report transport coefficients. For realistic acceptance of SO2 gas as SF6 alternative in long-term for high voltage applications, we discussed the utilization of these coefficients in study of various electrical breakdown related phenomenon to understand its dielectric and electrical insulating behavior during electrostatic discharge. We also predict numerical values of insulating properties in uniform electric field under steady state conditions such as electric strength, breakdown voltage and ionization constant for SO
2
gas using transport coefficients. For SO
2
gas, some of these properties and values are being calculated for first time.
