Abstract
A current measuring device for measuring the current through one or a plurality of conductors (L L L ) of an array of n conductors, n being a natural number≧2, comprises n+1 magnetic-field-sensitive sensors (S to S ) which are arranged such that two respective magnetic-field-sensitive sensors are arranged adjacent a respective conductor. A unit ( ) for reading out output signals of the magnetic-field-sensitive sensors is provided. Furthermore, the current measuring device is provided with a unit ( ) for calculating the current through one or a plurality of conductors on the basis of the read output signals and on the basis of coefficients which describe the influence of currents flowing through each of the n conductors and of a constant magnetic field on the output signal of each of the magnetic-field-sensitive sensors.
