| 摘要 |
The invention relates to a device for the isolated measurement of current, comprising a magnetic core that has an opening through which a primary conductor extends, and at least one measurement region that has at least two openings which divide each measurement region into at least three adjacent flux paths. The device additionally comprises a compensator winding that is wound about parts of the core outside of the at least one measurement region, at least two flux paths of the same measurement region, around which at least one exciter winding is wound, as well as at least one measurement winding that is wound about parts of said at least one measurement region. The invention also relates to a method for determining current in an isolated manner using an afore-mentioned device. |

1. A device (1) for measuring current, comprising:
a magnetic core (2) with
an opening (3) through which a primary conductor (L1) is routed, andat least one measuring region (4) with at least two openings (5), which subdivide the measuring region (4) into at least three adjacent flux paths (R1a, R1b, R2, R2a, R2b); a compensating winding (LC), which is wound around parts of the core (2) outside the measuring region (4); at least two flux paths (R1a, R1b, R2a, R2b) of the same measuring region (4), wound by at least one exciter winding (LS); at least one measuring winding (LM), which is wound around parts of the measuring region (4). |
