| Abstract: | In order to explore a new measurement method of partial discharge(PD) for motor,the electrical mechanism of PD and the situation of PD monitoring were discussed.An approach using ultrasonic for monitoring PD in a motor was proposed.Then several typical PD models of motor windings were constructed,and the PD monitoring system was developed.In the PD laboratory,four narrow-band ultrasonic sensors were used to detect the ultrasonic of the typical PD models.And under the same experiment conditions,the character... |
