For improving outgoing quality,installation quality and operational state of gas insulated metal encloses switch-gear,this paper proposes measures to improve operational reliability of GIS in aspects of engineer,installation commissio-ning,handing over acceptance,operational maintenance and technical advancement and applies in Guangdong power grid. After implementing the above measures in Guangdong power grid,it is found several GIS manufacturing problems and insu-lation defects in operation.In addition,significant and emergent defect rate of GIS decreases and short circuit insulation ac-cidents decline.Application effectiveness indicates that these measures are useful to realize overall process management for GIS quality from the source which is able to solve problems of multiple GIS faults.
