<p>In the electrical system described, a central control unit (13) sends signals on a data-transmission line (16) to a plurality of peripheral control units (14a, 14b, ... 14n) associated with the electrical sockets (11a, 11b, ... 11n) of the system. The peripheral units in turn receive and send signals on the same line (16). The signals contain address data for the peripheral units and commands for activating and de-activating the sockets. The sockets are activated and de-activated by means of switches (12a, 12b, ... 12n) controlled automatically by the peripheral units according to priority levels which are assigned to them and can be selected on the associated peripheral units, and on the basis of the criterion that, at any moment, the system must be supplied with the maximum power demanded as far as the maximum power available (Pmax) allows. <IMAGE></p> |
