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

Effect of Moisture inside sf 6 Gas Insulated Switchgear

Nov 17, 2011 · When switching is done in a gaz sf6 Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and sf 6 gasses will quench the arching in order to prevent it from spreading.Get price
