Abstract
Equipment (1) for measuring the energy consumption of branches (11-N) of an electrical network (10) which comprises a single voltages measuring device (2) connected upstream of the branches of the network so as to measure the voltages of the network in a centralized manner, and several dedicated current measuring devices (3) connected to each branch of the network so as to measure the currents on the branches of the network. The measuring devices (2, 3) are connected by network cable (6) allowing digital communication of the voltage measurements to the current measuring devices (3), which comprises a processing unit (33) for calculating the energy consumption of the analyzed branch of the network. The voltage and current measurements are performed by sampling, and the sampling frequencies are compared and adjusted automatically so as to synchronize the current samples with the voltage samples.
