Basic Research Equipment of Gas-insulated Bus Modelusing High Pressure SF6 SubstitutePurpose: To elucidate discharge phenomena and practical insulation
performance of environmentally friendly gases (compressed N2 or CO2),and estimate the possibility of using environmentally friendly gases as
an alternative insulation gas for practical gas-insulated apparatuses.
Moreover, we will investigate the possibility of a next generation gasinsulated apparatus (gas-insulated bus or gas-insulated transmissionline) using a hybrid gas insulation system that has the combined features of a solid insulator and a dielectric gas by discussing the basic insulation characteristics of hybrid gas insulation system.
