METHOD AND DEVICE FOR MEASURING THE CURRENT IN A THREE-PHASE NETWORK

摘要

1. Method of measuring the current drawn by a load from a three-phase AC network, characterized in that it comprises : - measurement from the AC network side of the difference between the currents flowing in two of the supply phases, - determination of the absolute value of this difference, and - assignment to the absolute value of the resulting signal of a correction coefficient k so as to obtain an output signal representative of the current flowing through the load.
