摘要
阐述了超声波测量变压器局部放电的机理及定位系统的组成、局放超声波信号的频谱分析、定位算法的实现,最后指出超声定位的注意事项及局限性。
This paper introduced the work principle of Ultrasonic to measure partial discharge（PD）in transformers ,and the composition of positioning system. The ultrasonic signal PD＇s spectrum, and the implementation of positioning algorithm has been analyzed. Finally, the note and the limitations of ultrasonic positioning - setting was given also.
