  • The SF6 Decomposition Mechanism: Background and

    Jan 24, 2017Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and otherCited by: 1

    Thats hats why GIS requires less room to be operated. ii) As in SF6 the arcing is under controlled and safe ,the fear of substation breakdown is least. iii) In GIS, corona effect is minimized. So power lost due to corona effect is less. iv) The AIS Circuit Breaker has a life span of normally 10 operations.
