sf6 emissions Storage Systems for Very High Voltages

sf6 emissions Storage Systems for Very High Voltages

Currently, there are no available substitutes for SF6 in high voltage applications. Fugitive emissions of SF6 can escape from gas-insulated substations and switch gear through seals, especially from older equipment. The gas can also be released during equipment manufacturing, installation, servicing, and disposal.
