SYSTEM AND PROCESS FOR THE MEASUREMENT OF THE ELECTRIC ENERGY CONSUMPTION OF A PLURALITY OF CONSUMERS

摘要

The present invention refers to a centralized system and process for measuring, registering, reading and billing data refer- ring to electric energy consumption of a plurality of consumers (14-17), whi ch receive the electric energy through a plurality of re- spective consumer connecting cables (18-21), connected to a main electric energy inlet cable (12) which, in turn, is connected to the electric energy distributing network (11). The system object of this invention basically comprises a voltage sensor (27); a plu- rality of energy transducer modules (ETMs) (28-31), each one connected to a respective consumer connecting cable (18-21) and including a current sensor (34) connected to an energy transducer circuit (3 5} connected to said voltage sensor (27) and capable of generating, in its output, signals corresponding to the current and voltage present at the respective consumer connecting cable (18-21); and a register/concentrator module (RCM) (26) having a memory and connected to the outputs of the several energy transducer circuits (35), and being capable of processing the said signals corresponding to current and voltage for their trans- mission or visual exhibition. The process of the present invention basically comprises the steps of measuring the current and vol- tage present in each consumer connecting cable (18-21); generating signals corresponding to such current and voltage; sending the said signals to a register/concentrator module (RCM) (26) having a memor y and capable of processing the said signals for their transmission or visual exhibition.
