Abstract: A current measurement system comprising a multi-phase open loop current transducer for measuring phase currents (I1, I2, I3) flowing in a plurality n of primary conductors of a multi-phase electrical system. The transducer comprises a housing, a magnetic core including first and second core parts and a plurality n+1 of magnetic field detectors mounted in the housing between the first and second core parts in which portions of the primary conductors traversing the current transducer housing are positioned. The system further comprises a non-volatile memory in which information on at least one coupling matrix (K), pre-defined in a calibration procedure, is stored.

Abstract: A method for dynamically compensating for the offset error of an acquisition system includes a current sensor to measure or estimate the current passing through an actuator of a electrical apparatus that is electrically supplied by an AC voltage, the acquisition system having a predetermined offset value, the method includes determining a plurality of periodic temporal operating ranges of the actuator in order to dynamically apply a compensation sequence for the offset error of the acquisition system, executing the compensation sequence during any one among the plurality of determined temporal operating ranges, the synchronization between the any one of the determined temporal operating ranges of the actuator and the execution of the compensation sequence being performed using a synchronization system including a synchronization module designed to identify reference times from the AC supply voltage of the sector.
