Breakdown Gradients in SF6-N2, SF6-Air and SF6-CO2 Mixtures
IEEE Transactions on Electrical Insulation, 1980 A method to calculate the uniform field breakdown gradients for SF6-N2, SF6-air and SF6-CO2 mixtures is discussed. Calculated values of the breakdown gradients in these mixtures are compared with experimentally measured values using plane-plane electrode configuration and direct applied voltages.

The suitability of N2 to replace SF6 in a triggered spark-gap switch for pulsed power applications [PDF]
, 2009 The high dielectric strength of sulphur hexafluoride (SF6) when compared with other gases, coupled with safety benefits such as non-flammability and non-toxicity, has seen the widespread use of SF6 for the insulation of switching components. However, SF6
