Abstract:
1. A method for detecting a magnetic characteristic variable in a section of a core permeated by a magnetic flux, the method comprising: branching off a portion of the magnetic flux from the core and passing the branched off portion via a magnetic shunt branch, in which at least one non-ferromagnetic gap is formed, disposing a shunt part in the shunt branch, wherein the magnetic material of the shunt part is not saturated, winding at least one section of the shunt part with at least one sensor coil in which the branched-off portion of the magnetic flux generates a sensor signal by induction, and determining 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.
