Abstract
A technique is provided for detecting a magnetic characteristic variable in particular the magnetic field strength in a section of a core permeated by a magnetic flux. A portion of the magnetic flux is branched off from the core and passed via a magnetic shunt branch, in which at least one non-ferromagnetic gap is formed. A shunt part is disposed in the shunt branch, wherein the magnetic material of the shunt part is not saturated. At least one section of the shunt part is wound with at least one sensor coil in which the branched-off portion of the magnetic flux generates a sensor signal by induction. The magnetic characteristic variable is determined from the branched-off portion of the magnetic flux or a variable derived therefrom using a sensor and evaluation device to which the sensor signal is fed.
