A gas insulated switchgear is used which is housed in a metal container filled with an insulating gas such as 6 gas. This gas insulated switchgear (GIS) generally includes a PT for measuring voltage. Conventionally, in multiple busbars such as double busbars, by concentrating the PTs of each busbar in the same location, work efficiency during measurement can be improved and maintenance and inspection work can be easily carried out. That's what I was doing.

If installed, the main bus bar 9a is used to prevent interference between the PTs.
9b間の間隔L2を大きくする必要があった。その結果
、ガス絶縁開閉装置の高さが高くなるので、安定性が大
幅に低下していた。It was necessary to increase the distance L2 between 9b. As a result, the height of the gas-insulated switchgear increases, resulting in a significant decrease in stability.
