<p><P>PROBLEM TO BE SOLVED: To provide a low-cost current detector which reduces a change of a measuring current due to an induction of other phase. <P>SOLUTION: The current detector comprises Rogowskii coils 1a to 1c respectively attached to a plurality of conductors supported to a tank; output voltage detecting circuits 12a to 12c for detecting output voltages of the coils; and a correction processing circuit 13 for processing to correct by considering an induced current flowing from other conductor based on the output voltages of the detecting circuits, and outputting correction processing results as the currents flowing to the respective conductors. <P>COPYRIGHT: (C)2004,JPO</p> |
