摘要： The invention relates to a compensation current sensor, comprising a magnet core (M4), with a first section around which a secondary winding (S4) is wound. A magnetic field probe (MS4) is arranged in the vicinity of the secondary winding (S4). A primary winding is magnetically coupled with the secondary winding (S4). A metal screen (A4) is provided at a distance from the magnet core (M4). On the plane, on which the magnet core (M4) lies, the shield (A4) surrounds the magnet core (M4), with the exception of a side opening, whereby part of the opening is in the vicinity of the magnetic field probe (MS4) and arranged and configured such that magnetic flux which passes through the shield (A4), partially passes through the magnetic field probe (MS4).

摘要： The invention relates to a current transformer comprising a primary conductor, a secondary winding and a soft-magnetic core, whereby the primary conductor and secondary winding are electrically insulated from one another and are magnetically intercoupled via the core. In addition, a current to be detected is injected into the primary conductor, and a compensating current is injected into the secondary winding. According to the invention, an additional conductor is provided which is electrically connected in parallel to the primary winding, and which is situated in the area of the core at which a flux rise occurs, whereby the flux rise is at least partially compensated for by the flux elicited by the current flowing in the additional conductor.
