Abstract
Apparatus and methods provide a current sensor system including a plurality of current sensors positioned proximate a plurality of conductors. Each conductor is configured to carry a current to be measured. Each current sensor comprises one or more magnetic field sensing elements configured to generate a respective magnetic field signal indicative of a detected magnetic field. The plurality of current sensors includes a first number of current sensors and the plurality of conductors includes a second number of conductors such that the first number is at least one more than the second number. A controller is coupled to receive the magnetic field signal from each of the current sensors and, for each magnetic field sensing element, is configured to characterize a magnetic coupling between the magnetic field sensing element and each of the plurality of conductors.
