Substations - EMFs is the one type of substation which can sometimes give markedly raised magnetic fields beyond its own confines. Cabinet - built into a fully-enclosed cabinet. Outdoors - the separate components are mounted on the ground and enclosed by a metal or wooden fence.
Design control and protection for medium voltage ... The 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.
