| description | The invention relates to a method for measuring a three-core power cable core wire, and belongs to the field of manufacturing and detection methods of three-core power cables. According to the technical scheme, two magnetic sensors are symmetrically installed on the surface of a three-core power cable, after the excitation is applied to a certain single-phase core wire, the magnetic sensor is usedfor measuring the tangential component of the magnetic induction intensity of the surface of the cable where the magnetic sensor is located; according to the measured values of the two magnetic sensors, the geometric relation between the ampere loop theorem and the position structure between the core lines is utilized, the distance from the center of the single-phase core wire to the center of the cable, and the included angle between the connecting line of the center of the single-phase core wire and the center of the cable and the y-axis are solved, namely the position of the single-phase core wire is obtained; the |
