On the back panel is a fragment of the installation of electric lighting in the apartment. The shafts of all electric machines are mechanically connected to each other by means of couplings. Control of the supply to the stand of three-phase voltage is carried out by indicator lamps. In the right part of the stand there is a functional block for studying the asynchronous motor and the drive based on it. On the left are the start-up devices used in this scheme. In the central part of the panel the rear devices for researching the DPT and the transformer.

To assemble the studied circuits, the corresponding elements should be connected with connecting wires(jumpers) according to the schematic diagrams given in the methodical instructions.

A set of methodical and technical documentation intended for the teaching staff is attached to the stand. To assemble the studied circuits, connecting wires (jumpers) should be used to connect the corresponding elements according to the schematic diagrams given in the methodical instructions. Aset
