500kv gis substation monitoring

To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (sf6-gas), at high pressure. sf6-gas 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
