Zusammenfassung
(EN) The present invention relates to an arrangement for measuring electrical currents, the measurement being based on magnetic fields. By means of at least one sensor element (10) which is sensitive to magnetic fields, the current is measured in a bent, particularly U-shaped, conductor element (2) comprising at least one conductor section (4, 30) which is active in terms of current measurement and at least one conductor section (5, 32) which is parasitic in terms of current measurement. In the region of the conductor section (4, 30) which is active in terms of current measurement, the sensor element (10) is oriented, particularly twisted with respect to the conductor section (5, 32) which is parasitic in terms of current measurement, tilted with respect to the conductor section (5, 32) which is parasitic in terms of current measurement and/or height-adjusted with respect to the conductor section (5, 32) which is parasitic in terms of current measurement, such that the magnetic field of the conductor section (4, 30) which is active in terms of current measurement is oriented substantially in the direction of sensitivity (70) and the magnetic field of the conductor section (5, 32) which is parasitic in terms of current measurement is oriented substantially not in the direction of sensitivity (70), particularly perpendicular to the direction of sensitivity (70).

本发明涉及一种用于基于磁场测量电流的设备。通过至少一个磁场敏感传感器元件(10)来测量有角度的特别是U形的导体元件(2)中的电流,其中所述导体元件(2)包括至少一个对电流测量有用的导体区段(4,30)以及至少一个寄生于电流测量的导体区段(5,32)。所述传感器元件(10)在所述对电流测量有用的导体区段(4,30)的区域中被以下述方式设定朝向:特别地相对于所述寄生于电流测量的导体区段(5,32)扭转、相对于所述寄生于电流测量的导体区段(5,32)倾斜和/或相对于所述寄生于电流测量的导体区段(5,32)竖直偏移,使得所述对电流测量有用的导体区段(4,30)的磁场被大体上沿着敏感方向(70)设定朝向,并且所述寄生于电流测量的导体区段(5,32)的磁场被大体上不沿着所述敏感方向(70)设定朝向——而是特别地与所述敏感方向(70)成直角。
