Abstract

A current sensor comprising a primary conductor for conducting a current that is to be measured, at least two magnetic field probes for measuring magnetic fields, and a magnetic core, which has a closed ring structure having three or more corners that encloses the primary conductor, wherein each magnetic field probe is arranged on the magnetic core or in recesses in the magnetic core.
