Gas-Insulated Substations - GIS

Sulfr hexafluoride is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. sf 6 has two to three times the insulating ability of air at the same pressure. sf 6 is about 100 times better than air for interrupting arcs.

gaz sf6 gas pressure for the insulating use is preserved below 2.5 bars while Sulfr hexafluoride gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn’t accessible for high voltage, so for C-GIS system above 72.5 KV, only insulating gas is utilized both for insulation and interruption medium.

The Problem with Humidity in gaz sf6 Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.
