Abstract

Gas insulated bus (GIB) using SF6 gas has widely been applied in the world, because it has the advantages in reliability and in minimizing installation space. However SF6 is identified as a potent greenhouse gas and thus the efforts in preventing the release of SF6 in the environment, the study on recycling SF6and the research for alternative gas are now being performed1. in designing a GIB using alternative gas, there are many application problems such as a selection of alternative gas and its rated pressure to maintain the required dielectric and heat transfer performance. the problems on recycling SF6 are also essential in applying alternative gas using SF6 such as SF6/N2 mixtures.
