Device for a central and automatic reading, registration and control of energy consumption meters (12) located at consumers. The communication between producer and consumer is made through codified signals, which by way of modem (22) are superposed on the line voltage of the power distribution network (S, R, T). Thus the charge per unit energy consumed can be easily changed from a time to another. The charge can therefore always and effectively be related to the cost of production for the energy, and thus a more equitable charging system can be created, which promotes saving of energy. |
