IR SF6 leakage and quality for HV MV

IR SF6 leakage and quality for HV MV

2020-7-67-Gas quality: A first indicator for end-of-life of non-SF6 gases and gas mixtures would be the gas lifetime statement of the equipment manufacturer. A gas quality check (if possible) might indicate that the equipment can be used longer, or that the gas has to be replaced if its end-of-life condition is reached.
