Abstract
In a method for measuring a current, a plurality of flux-gate field sensors is arranged with radial symmetry on a first circumferential path, and a plurality of Hall sensors is arranged with radial symmetry on a second circumferential path such that a one of the flux-gate field sensors is placed adjacent a one of the Hall sensors, with the flux-gate field sensors having a sensitivity which is higher by a factor 5 to 20 than a sensitivity of the Hall sensors. At least one of the plurality of flux-gate field sensors is evaluated so as to determine a current intensity, when two of the flux-gate field sensors generate measurement values within a measurement range, or at least one of the plurality of Hall sensors is evaluated so as to determine a current intensity, when the measurement values of the two flux-gate field sensors are outside of the measurement range.
