摘要
在对变压器绕组的频率特性进行分析的基础上，根据小波变换和傅立叶变换的特性，综合运用这两种变换对信号进行处理，提出了一种新的对大型电力变压器绕组内部的局部放电进行精确定位的方法。现场模拟试验表明，该定位方法正确可行。
On the basis of the analysis of transformer windings frequency characteristic, a new electrical method of partial discharge location in transformer windings is given in this paper. According to the different traits of the Wavelet transform and Fourier transform, the signals were processed by the aid of the two ways. Test results with simulated partial discharge in transformer windings have proved that the way of location is right and valid.
