Research on an Underground Electricity Cable Path Detection System

A system of underground power cable path detection based on electromagnetic method is proposed, the system aim at the test site containing both running and non-running state of the cable, measure the three components of the magnetic field by three-axis high sensitivity magneto-resistive sensors above the ground, use pre-processing circuit to eliminate interference, then calculate the specific location of underground cables and the path toward by the magnetic field detection model, complete the intelligent path detection of the running and non-running cables. Mat lab and Multisim simulation verify the feasibility of the magnetic field detection model and pre-circuit, respectively, indicating that the system of underground power cable path intelligent detection has good practicality.
