<p><P>PROBLEM TO BE SOLVED: To provide a device for detecting a polyphase current which accurately detects a current to be measured without receiving the influence of the other phase even with a primary conductor arranged closely to detect the polyphase current. <P>SOLUTION: Since a structure in which a magnetoelectric transducer for detecting the magnetic flux of a face outside direction is installed on a counterbore part provided on the primary conductor or a U-shaped formation part exits, it is applied from the other phase to reduce the influence of the magnetic flux which becomes an error so as to enable miniaturization and high precision, as the device for detecting a polyphase current. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
