Sensor arrangement for use as e.g. alternating current sensor arrangement for determining current in home, has conductor, where sum of angle encloses straight line and sensor with another straight line with certain value

摘要

The arrangement (135) has first, second and third conductors (110, 115, 120) intersecting parallel to each other in a plane (125) at equal distances. Multiple magnetic field sensors (140) are arranged at equal distances along a circular line (145) circulating the first conductor in the plane. A sum of a twisting angle (a0) encloses a straight line (155) by the first conductor and one of the magnetic field sensors with another straight line (160) by the conductors in the plane as large as 90 degrees per Newton. A midpoint (150) of the circular line lies within the first conductor. The magnetic field sensors are selected from hall sensor, giant magneto resistance-sensor, anisotropic magneto resistive-sensor, colossal magneto-resistive-sensor and tunneling magneto resistance sensor. An independent claim is also included for a method for determining current.
