Zusammenfassung:A current measuring system for measuring a current through a conductor is described. The system includes a first sensor configured to measure a first magnetic flux and to generate a first signal proportional to the first magnetic flux. The system also includes a second sensor configured to measure a second magnetic flux and to provide a second signal proportional to the second magnetic flux, the second sensor having a higher sensitivity to stray magnetic fields than the first sensor. The system also includes a processor coupled to the first sensor and the second sensor and configured to receive the first signal and the second signal. The processor is further configured to determine a presence of a stray magnetic field by comparing the first signal and the second signal.
