摘要
在频率响应分析法检测变压器绕组变形中将测量频域分段，并分别计算其特征值的方法，尝试直接利用测量数据的特征值，而非过去依赖经验来判断变压器绕组的状态。
Frequency Response Analysis method ( FRA ) has been used for transformer winding deformations for many years and obtains favorable effect. In this paper the measured frequency rangs is divided into three sections and the feature values on the whole range and every section are calculated. Based on all these feature values the judgement becomes easy and the correctnessincreases.
