  • INDUSTRIAL TRAINING REPORT ON 400/220kV

    The reasons for implementing GIS are can be understood by comparing it to AIS(Air AIS Insulated Switchgear) i) As in EHV, the conventional type of circuit breaker needs large space for enclosing the arc evolved at the instant of switching.But in SF6 environment the probability and intensity intensity of arc build up is very rare.

    If the gas is used solely for insulation it can be mixed with nitrogen. An SF 6/N 2 mixture of 20/80 % has still 70–80 % of the insulation properties of pure SF 6 [3]. However, to extinguish the electric arc in high voltage circuit breakers during current inter-ruption SF 6 has proved to be unique. As a consequence intensive
