 Let's shed a more detailed light on the boundaries of a sub grid as of our definition.
 This especially is important, if the switchgear of the transformer is modeled in detail.
-We defined, that all nodes in upstream direction of the transformer, including those, which are connected by switches *only*
-(therefore are within the switchgear) are counted towards the superior sub grid structure (here "1"), because they belong
-to a different voltage level.

 If a switchgear should be operated by the inferior grid, one can set the operator, that is used in the inferior grid, for
 the switchgear. This can be necessary, if we assume, that the interest to operate on the given switchgear will most likely
 be placed in the inferior grid structure.
