The level of humidity in SF 6 -insulated switchgear must be kept below its water saturation point. If the gas is too humid, it loses some of its insulating properties; corrosion and dangerous leaks can also occur. A complete SF 6 handling instrument monitors the …

Water: The Most Powerful Impurity in SF6 Gas-Insulated Switchgear
Leo Lopez | SF6 Gas SolutionsSulfur 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 …
