Abstract
This paper presents an acoustic emission(AE) technique using ultrasonic sensors to diagonize power transformers. Conventional methods detect and measure the electrical signal of the partial discharge(PD) of transformers in operation. The proposed techniques measures the acoustic signal generated by the partial discharge, and counts the number of the waveforms above a threshold to diagonize transformers. Experiments showed that the proposed method improved diagonosis capability over the conventional PD method.
