  • SF6 Circuit Breakers - Construction, Types and Working

    2021-3-17In an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium.. The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck

  • INDUSTRIAL TRAINING REPORT ON 400/220kV

    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.
