METHOD FOR DETERMINING POWER CONSUMPTION IN AN ELECTRICAL INSTALLATION AND ALTERNATING CURRENT ELECTRICAL INSTALLATION

摘要

According to the invention a group comprising a plurality of individual distribution branches connected in parallel is connected to an alternating current power supply. The method comprises the following steps in which: a) detection of a change in the electrical consumption of one specific branch among the branches; and b) determination of the individual power consumption of the specific branch based on a measurement of the total voltage (U) which is substantially constant during the change measurements of the intensity and phase shift values (I I ? ?) of the total current before and after the change and measurements of the intensities (l I) of the individual current in the specific branch before and after the change.
