2018-1-10testing of indoor gas insulated switchgear (GIS) as specified in the following sections of this document. 2.0 Reference Standards Codes The SF6 gas insulated metal enclosed switchgear shall be totally safe against inadvertent touch of any of its live constituent parts. All parts of the switchgear should be

Assessment of Sulphur Hexafluoride (SF6) gas insulation. Testing SF 6 gas for impurities will therefore indicate potential issues with the switchgear.. Decomposition products arise during operation of SF 6 gas-insulated switchgear through arcing in moist or impure SF 6 gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear.

Gas-insulated Switchgear (GIS) Testing. Gas-insulated 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.
