Isolated DC current and voltage sensor with low crosstalk

摘要

A device for magnetic measurement that includes a DC magnetic field sensor having at least four discrete elements, each of the discrete elements being constituted by at least one coil and a magnetic material without remanence, where the at least four discrete elements are substantially identical. The magnetic field sensor includes a first discrete element orientated in a given direction, and a second discrete element associated therewith to constitute a first differential pair. The second discrete element being orientated in parallel but in an opposite direction relative to the first discrete element. The device further including two other discrete elements constituting a second differential pair substantially identical to the first differential pair. The two other discrete elements being parallel to the orientation of the first differential pair but are respectively orientated in an opposite direction to the first and second discrete elements of the first differential pair.
