gis substation leak check

This online engineering course provides a basic overview of Gas Insulated Substations (GIS) and GIS technology. A GIS is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as sulfur hexafluoride gas (SF6) as the insulating medium.
