  • Measurement of the ionisation and attachment

    Here €is the electric field,pzO is the gas pressure at 20 C and Nis the gas number density. The SF6 and air mixture is considered to be an important substitute for pure SF6 as an insulant at high voltage since, unlike the pure gas, the mixture has high dielectric strengths even in non-uniform fields.
