Abstract

See full text

A current measuring device includes a conductor in which detection target current flows, at least two magnetic sensors that detect change of magnetic field generated when the detection target current flows in the conductor, and a calculation unit that calculates magnitude of the detection target current from an output of the magnetic sensor. At least two magnetic sensors are provided at different distances from the conductor, and the calculation unit acquires distances between the magnetic sensors and the conductor to calculate magnitude of the detection target current using the distances.
