SF6 Gas Insulated Equipment

​​The electric power industry uses SF6 to insulate switchgears, circuit breakers and other equipment used in electricity transmission and distribution. To ensure the integrity of SF6 gas as an insulator, the amount of water vapor in SF6 gas should be kept to a minimum. Moisture may increase the formation of unwanted secondary decomposition products, which can lead to arcing and equipment failure. Vaisala offers convenient solutions for online monitoring of SF6 gas.
