The invention relates to a method of using magnetic sensors to measure each core line current of a three-core power cable and magnetic sensor installation deflection angles and belongs to the currentmeasurement method technology field. The technical scheme is characterized by adopting four magnetic sensors to measure the tangential component of magnetic induction intensity on a three-core power cable surface, wherein three magnetic sensors are arranged in a regular triangle mode, and one magnetic sensor and one of the other three magnetic sensors are centrally symmetrical about the center ofa regular triangle; using an optimization method to solve a nonlinear equation group, and according to the measured values of the magnetic sensors and the design parameter of the three-core power cable, acquiring each core line current of the three-core power cable, the installation angles of the magnetic sensors, and the deflection angle of the corresponding core line in the cable. The method hasan advantage that a problem that each core line current in the three-core power cable is difficult to measure during actual engineering and a problem that the installation angles of the magnetic sensors and the deflection angle among the cable core lines are difficult to determine are solved.
