A system for providing real-time modeling of an electrical system under management is disclosed. The present invention provides for the dividing wall to be constructed at least partly of an elastic material, the dividing wall to have a slightly overdimensional width and the dividing wall to be fixed in the column by the dividing wall exercising an elastic recovery force on the interior wall of the column. The Y-beam bridges the space between the X-stage carriages and is connected to the X-stage carriages via a flexible coupling.
