Introduction Since the introduction of Gas Insulated Substations (GIS) in the late 1960s, sulphur hexafluoride (SF6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, SF 6 has the major drawback of presenting a global warming potential (GWP) if released to the atmosphere, which is 23,500 times higher than CO 2 and a lifetime in the
