Three-Phase Cable Positioning Method Based on Triaxial Magnetic Sensors

The rapid and accurate positioning of transmission cables is crucial for ensuring the stable operation of power systems and improving the efficiency of cable fault repairs. However, existing transmission cable positioning technologies generally have defects such as low positioning accuracy, high algorithm complexity and significant application limitations, which weaken their effectiveness in practical applications to some extent. In view of this, a fast positioning method for three-phase cable is proposed in this paper, and the relationship between the magnetic induction intensity around the three-phase cable and the distance from the geometric center of the cable is derived. By combining a triaxial magnetic sensor array for magnetic detection, the location information of the three-phase cable can be determined, enabling its precise positioning. Finally, the feasibility of this method is verified through C OMSOL simulation a nd experiments, which has certain engineering application value.
