  • Dc Voltage Breakdown of SF6-Air and SF6-CO2 Mixtures

    Abstract: dc breakdown and corona inception voltages are reported for SF6-air and SF6-CO2 mixtures in positive and negative rod-plane gaps. These voltages are compared with values obtained for SF6-N2 mixtures. The results show that the breakdown voltages of SF6-air mixtures exhibit corona stabilization over a
