Abstract
The invention relates to a compensation current sensor, comprising a magnet core (M ), with a first section around which a secondary winding (S ) is wound. A magnetic field probe (MS ) is arranged in the vicinity of the secondary winding (S ). A primary winding is magnetically coupled with the secondary winding (S ). A metal screen (A ) is provided at a distance from the magnet core (M ). On the plane, on which the magnet core (M ) lies, the shield (A ) surrounds the magnet core (M ), with the exception of a side opening, whereby part of the opening is in the vicinity of the magnetic field probe (MS ) and arranged and configured such that magnetic flux which passes through the shield (A ), partially passes through the magnetic field probe (MS ).
