  • Health and environmental dangers of SF6-filled switchgear

    However, although SF 6 is inert during normal use, highly toxic by-products are produced that pose a serious health threat to the workers who come into contact with them when electrical discharges occur through everyday usage within SF 6-filled equipment [2]. SF 6 has been identified as the most potent and persistent greenhouse gas in existence. In fact, it has a global warming potential approximately 24 000 times greater than carbon dioxide [3].

  • Decomposition Mechanism of C5F10O: An Environmentally

    SF 6, the most widely used electrical-equipment-insulation gas, has serious greenhouse effects. C 5 F 10 O has attracted much attention as an alternative gas in recent two years, but the environmental impact of its decomposition products is unclear. In this work, the decomposition characteristics of C 5 F 10 O were studied based on gas chromatography–mass spectrometry and density functional theory.
