<p><P>PROBLEM TO BE SOLVED: To detect more properly the generation of partial discharge in a motor, especially generation of partial discharge between adjacent coils among a plurality of coils wound on a stator of the motor. <P>SOLUTION: Antennas 70-72 are mounted so as to be in contact with two coils, having a possibility of generating partial discharge between respective in-phase adjacent coils among coils in the U-phase, the V-phase, and the W-phase wound on the stator 30 of the motor 22, and generation of partial discharge between coils in each phase of the U-phase, the V-phase, and the W-phase based on an electromotive force (voltage) which is detected by the antennas 70-72. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
