Classification: CPC G | IPC G

Claim 7:
8. A current measurement method that is executed by a current measurement device comprising a plurality of triaxial magnetic sensors disposed so that a magnetic sensing direction and a relative position have a prescribed relationship, a noise remover, a sign adder, and a current calculator to measure a current flowing through measurement target conductors, the current measurement method comprising:
removing, by the noise remover, noise components included in detection results of the plurality of triaxial magnetic sensors;
adding, by the sign adder, a sign to the detection results from which the noise components have been removed, based on sign information of each of the detection results of the plurality of triaxial magnetic sensors obtained at a specific point in time; and
calculating, by the current calculator, a current flowing through the measurement target conductors by using the detection results to which the sign has been added by the sign adder.
