• An Introduction to Gas Insulated Electrical Substations

    This course provides an brief introductory overview of (GIS) or Gas Insulated Substations. A gas insulated substation (GIS) is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as Sulfr hexafluoride, or sulfur hexafluoride gas as the insulating medium.
