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