SWITCHGEAR AND SF6 GAS - gob.mx· PDF file1.2 Basic design requirement. Gas-tight enclosure SF6 is used in different types of electrical switchgear: • Modern, state of the art, High Voltage and Extra High Voltage switching devices (e.g. circuit breakers) use SF6 as an arc-quenching medium, almost exclusively. More integrated solutions, like the Gas Insulated Switchgear (GIS)
The Problem with Humidity in SF6 Gas-Insulated Systems hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).
