  • Western Power Distribution - SF6 Alternatives

    The project will improve on the current knowledge of SF6 alternatives. The test results will provide a clear indication on SF6 alternatives in 11kV RMUs. This will support the development of SF6 free switchgear. Reports generated through the project will be disseminated to other DNOs and other relevant stakeholders.

    The reconditioning process includes increasing the storage pressure of the gas to allow the start of SF 6 gas liquefaction followed by lowering the temperature by using two to three temperature changes below -40 degrees C. This further helps the liquefaction of SF 6 gas, thus separating other vapors such as N 2, O 2, and CF 4.Upon the start of the reconditioning process, the contaminated SF 6
