ABSTRACT ELECTRONIC METER FOR MEASURING ACTIVE AND REACTIVE ENERGIES IN A THREE-PHASE NETWORK A plurality of single phase energy sensors (DEl to DE6) each having a first input connected to a current converter and a second input connected to voltage converter supply energy pulses (E1= to E6+, E1- to E6-) of which the number represents the energy detected by the single phase sensor; the calculating device (20) is based on a microprocessor (MP) and comprises accumulating means controlled by the pulses delivered by the energy sensors for supply the active and reactive power measurements sought. In the case of a four-wire network, it is not necessary to use voltage transformers for the interphase network voltages. and the energy sensors supply pulses which represent Image and Image .
