<p>PURPOSE: To enable exactly detecting current in a conductor even in the case where another conductor is arranged close to the conductor in which the detec tion current is flowing, by arranging a non-magnetic conductor in the vicinity of a magneto-electric transducer element and grounding this non-magnetic con ductor. CONSTITUTION: The current flowing through a conductor 4 wound around a bobbin 12 is converted to voltage by a magneto-electric transducer 5. At this moment, even if another conductor 8 which carries alternating current, is arranged close to the conductor, the alternating current component caused by the current in another conductor 8, noise in other word, is eliminated by grounding via a non-magnetic conductor 6. By this, the overlapping of noise on the output voltage of the magnetoelectric transducer 5 can be prevented and the current of the conductor 4 is exactly detected.</p> |
