    Abstract. Sulfur hexafluoride (SF 6) is the insulator gas used in most of equipments handling high and very high voltages.Owing to its high global warming potential, SF 6 has been classified during the Kyoto conference on climate change among the greenhouse gases. Its emission in the atmosphere must therefore be reduced 1.InCited by: 1
