| 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).
