要約(英語): In modern automobiles, the ratio of the electric motors used has been increasing every year. Therefore, it is important to produce motors with high quality in automobile manufacturing. The quality of the motors depends on insulation characteristics of the stator coil of motors and the strict insulation test has been conducted during the manufacturing process of the stator. However, this test cannot show the defect point of the insulation and so it is difficult to reuse the stator by repair. If we could know the insulation defect point, the stator can be reused by minor repair and the productivity can be much improved.In a large scaled motor for a power plant, the electrical partial discharge due to the insulation defect at the stator coil has been monitored by non-wired measuring systems. However, this is the monitoring system whether the motor works normally or not. This is not used to predict the location of the electric partial discharge point.In this paper, we propose the measuring system to predict the insulation defect point due to electric partial discharge.
