Abstract: A test installation provides for producing a residence that has a dwelling on the one hand and a test laboratory on the other. The dwelling and the laboratory are electrically powered by separate electric power supplies. The dwelling and the residence are linked to one another by sets of channels passing through a slab of the residence and opening to abutting cable trunks opposite the test laboratory. It is shown that in this way, connections joining measuring apparatus with apparatus for processing the measurements located in the test laboratory can be placed in these channels and this cable trunk. In this way, these connections are always placed correctly at the same location and do not interfere in the measurement. To increase the efficacy of the system, it is provided that a test bench is produced that is independently powered by an electrical perturbation signal that has been measured previously in the dwelling.
