摘要： A current specifying device may comprise a plurality of sensors configured to be attached to an outer side of a sheath of a multicore cable, each of the plurality of sensors being configured to detect a magnetic field strength of a magnetic field generated by current flowing in the multicore cable, and a controller configured to specify a current value of the current flowing in the multicore cable by using the magnetic field strength detected by at least one sensor among the plurality of sensors, wherein the controller may detect a change in a relative relationship of the magnetic field strengths detected by at least two sensors among the plurality of sensors.
