SF6 Decomposition Charging for Transformers

SF6 Decomposition Charging for Transformers

Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 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
