GAS INSULATED SWITCHGEAR - nationalgrid.com· PDF fileat nominal voltages of 400 kV, 275 kV, 132 kV and 66 kV unless otherwise agreed with the user as defined in the Bilateral agreement. The principles of this document applies to equipment connected at other voltages". This document defines the functional and performance requirements for gas-insulated switchgear (GIS).
Gas-insulated Switchgear (GIS) Testing - OMICRON switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS.
