gis substation valve MAINTENANCE AND TESTING in Denmark

Jan 02, 2014 · Gas Insulated Substations are used where there is space for providing the substation is expensive in large cities and towns. In normal substation the clearances between the phase to phase and phase to ground is very large. Due to this, large space is required for the normal or Air Insulated Substation (AIS).
