Gas insulated switchgear is a
Gas insulated switchgear is a metal closed type switchgear that acts as an insulator between live parts and soil metal casing with sulfur hexafluoride (SF6) gas. High voltage equipment is housed in a gas tight container filled with a degassing gas called SF6.
These GIS switchgear are available in voltage ranges from 12 kV to 800 kV.
Medium voltage GIS are available up to 52 kV. Its pressure of SF6 gas must below 2.5 bar. Medium voltage GIS system has vacuum circuit breaker as the interrupting medium and SF6 gas as the main insulation. The substation using the SF6 gas for both insulation and interruption are also available in medium voltage. One is designed to act as an insulator and the other as an interrupter to equipment.
This Medium voltage system is covered in standard IEC 62271-107. Standard of High voltage GIS for class above 52 kV are covered in IEC 62271-108. Click here to know IEC 62271-100: 2017 Standard of High-voltage switchgear and control-gear.
