The method, according to the invention, for determining conductor currents is based on metrological detection of vector magnetic field strengths in the total magnetic field of a multi-conductor system. The individual conductor currents are calculated on the basis of the measured field strengths. A measuring arrangement suitable for carrying out the method comprises a plurality of sensors (S1 to S3) equivalent to the number of conductors or, in the case of a three-phase system, also only two sensors, which are arranged in the total magnetic field close to the three-conductor system (1) and inside a magnetic screening device (4) and are connected to an evaluation device (5). <IMAGE> |
