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 sf6 gas, or sulfur hexafluoride gas as the insulating medium.Get price

Operation and Maintenance of a Gas Insulated Substation

A major difference between conventional air insulated substations (AIS) and the gas insulated substations (GIS) is that the gaz sf6 gas insulated electrical components are placed within an earthed, pressurized metallic container. This is a significant change in operating the switchgear with circuit breakers, disconnectors, and switches earthGet price
