GIS - There are two terms presented in IEC “Gas Insulated Switchgear” and IEEE “Gas Insulated Substations.” In IEEE C37.122 - Gas insulated switchgear (GIS): a compact, multicomponent device, enclosed in a grounded metallic case in which the basic insulating medium is Sulfr hexafluoride gasGet price

An Overview on GIS (Gas Insulated Substation) Engineering

GIS substations use sf 6 gas that reduces the distance needed between active and non-active switchgear parts resulting in smaller overall space requirements (ideal for congested city areas). GIS substations also offer lower operating and maintenance costs; and are less sensitive to pollution, salt, sand and large amounts of snow.Get price

Measuring partial discharge in GIS - Think Grid

To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (SF 6), at high pressure. SF 6 has excellent dielectric properties and is used as the insulating medium between the phases and between the phases and earth. As a consequence, a GIS is much more compact.Get price
