Design control and protection for medium voltage switchgear· PDF fileThe switchgear needs to be able to break and connect generators to load banks or to the grids. Open switchgears are big and they needed a lot of equipment. The switchgear is going to be a GIS (Gas Isolated Switchgear). This will be 10-15% smaller than an open switchgear. GIS are used where you cannot use an open switchgear, which may be because
