Partial discharge (PD) is the main cause of electric equipment degradation. PD location can provide the scientific direction and analysis for equipment condition monitoring. The phased-ultrasonic receiving-planar array transducer for PO location in transformer is studied in this peper. The operation environment and material properties of transducer are analyzed. The center frequency of transducer is 150 kHz and its bandwidth is 100 kHz. The piezoelectric source and oil interstitial defect are used to detect the transducer's performance in lab. Experimental results show the transducer has perfect ultrasonic receiving characteristics. The successful developments of this sensor provide a good foundation for PD location in transformer using phased-ultrasonic receiving-planar array transducer.
