<p><P>PROBLEM TO BE SOLVED: To provide a current measuring device capable of correctly measuring current. <P>SOLUTION: A first magnetic sensor 14a arranged in a narrow gap Ga and a second magnetic sensor 14b arranged in a wide gap Gb are different in the magnetic flux density and sensitivity. But the amount of the residual flux Br is same. Thereby, the current can be correctly measured by correcting the same amount of the residual flux Br portion for reducing the affection by detecting the magnetic flux with the first magnetic sensor 14a and the second magnetic sensor 14b. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
