what is the difference between indoor & Out door substations
Answer Posted / anup mohan
Comparitively lower voltage substations are termed to be indoor substation. It can also be termed as industrial substation which is so cz.. such substations are for industrial purposes.... 6.6,11,33,66kV are indoor SS..
Higher voltahe i.e 132/33,220,400,765kV are outdoor SS...
I reckon the above posts were cz of confusion between AIS substation and GIS substation. The former being Air Insulated S/S and later being Gas Insulated S/S.
GIS are compact... equipments and its connections/terminations are closed and gas insulated (SF6) which is exactly oposite to that of AIS..
