News Room : GE Grid Solutions monitoring is done with g3 as it was with SF6. Traditional sensors (temperature-compensated pressure switches) have only to be adapted to the updated pressure. Digital sensors for on-line monitoring do not require changes; just the software needs updating according to the physical properties of the g3 mixture. Digital density sensor

SF6 Gas Use in Electrical Applications - SF6· Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and …
