Estimation of Cross-Sectional Size of Gas-Insulated Apparatus Using Hybrid Insulation System with SF6 Substitute
SF6 has been identified as a greenhouse gas with a long atmospheric lifetime1. Therefore, recycling guidelines for SF6 in electric power apparatus have been studied, and the reduction in the amount of SF6 released into the atmosphere has progressed2. In the long term, it is preferable to reduce the amount of SF6 used. Therefore, it may be important to discuss the possibility of using environmentally friendly gases as an alternative insulation gas for practical gas-insulated apparatus.
