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
