SF6-alternatives detection system for 220kv

SF6-alternatives detection system for 220kv

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.
