Abstract
A current measurement system comprising a multi-phase open loop current transducer for measuring phase currents (I, I, I) 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+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.
