Pure SF 6 is an excellent insulator in electric switchgears, but humidity in the gas decreases its insulating ability and can also result in very harmful decomposition products for humans, machinery, and the environment. Created in partnership with a European utility …
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 …
Sulfur 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 …
