A GIS uses superior dielectric gas and sulfur hexaflouride at moderate pressure for insulation.
It is mostly used where space is expensive or not available. In a GIS, the active parts are protected from the deterioration from exposure to atmospheric air, moisture and contamination.
According to the official, a 400-kV power transmission line has already been completed in the region and as soon as the substation goes on stream, the 400- kV electricity that comes from South Pars 1 gas-fueled power plant will be converted to 132-Kv before its distribution in the refineries.
A substation reduces the high voltage of power transmission to suitable voltage for supply to consumers. The hot and dry climate in Yazd is ideal for harvesting solar energy. ■
