Abstract
The present disclosure relates to electrical conductors. The teachings herein may be embodied a current-measuring devices and/or methods for determining an electric current in an electrical conductor. For example, a method for determining a magnitude of an electric current in an electrical conductor may include: measuring output signals from a plurality of magnetic-field sensors arrayed around the electrical conductor; setting a compensation current through a compensation coil surrounding the plurality of magnetic-field sensors based on detected output variables of the magnetic-field sensors; and determining the magnitude of the electric current through the electrical conductor based on the set compensation current through the compensation coil.
