碩士 === 中原大學 === 電機工程研究所 === 95 === The gas insulated switchgear equipment (GIS) has been widely applied on the substations of utility and customers due to the advantages of reducing the substation space requirement significantly, and making the substation as indoor type thus increasing the benefit of land and preventing the environmental impact for less maintenance of equipments. All of these advantages of GIS will contribute to safety and reliability of substation . In practice, however, some problems of unsuitable grounding and maintenances are arisen from GIS installation which may affect the operation safety of GIS. The grounding problems cover GIS and its interfaces with the cables, while the maintenance problems concern the items, work contents and their reference basis and related difficulty. These problems are discussed in this report based on the study results from literatures and the technical information from manufactures of GIS. Where in ,in addition, improvement strategies can be found.
