<p><P>PROBLEM TO BE SOLVED: To provide a current detection system which can perform high-accuracy detection, even in a high magnetic field intensity region. <P>SOLUTION: A current sensor 2, provided separately from a current sensor 3 for performing current detection by the magnetic balance method, is fixed in the vicinity of a bus bar 1. A control section 9 controls a motor 7 according to the magnetic field level/current value detected by the current sensor 2, changes the distance between the bus bar 1 and a current detection section 5, and detects a current passing through the bus bar 1, according to a magnetic field level detected by the current sensor 3 and the adjusted result of a feedback current. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
