sf 6 Insulated Equipment

Time-based maintenance strategy for gas-related maintenance works is easily adaptable to high voltage gas-insulated equipment with non-sf6 gas gases and gas mixtures. Compared to sf 6, if gas mixtures are applied to GIS, the mixing ratio is one additional gas-related indicator to be measured or monitored to evaluate the need
