    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.
