    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 for maintenance actions. When handling gas mixtures, the main difference to SF 6 is that additional efforts for maintaining the correct mixing ratio during filling and reclaiming works are needed. The liquefaction behaviour of single gas components has to be considered which may affect the required gas handling time during maintenance
