Original Abstract Submitted
A current measurement apparatus includes a corrector. The corrector calculates an error arising in a measured value of at least one target phase current due to magnetic flux generated from each of multiphase power lines in accordance with an error factor defined for each multiphase power line with respect to the at least one target phase current. The error factor defined for each multiphase power line with respect to the at least one target phase current is a constant value or a variable determined based on (i) one or more shields located between the current sensor and the corresponding multiphase power line and (ii) a distance between the current sensor and the corresponding multiphase power line. The corrector corrects the measured value of the at least one target phase current based on the calculated error.
