Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf6 gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what sf6 gas can do in centimeters.Get price

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 insulating 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 Sulfr hexafluoride gas insulated electrical components are placed within an earthed, pressurized metallic container.
