本文提出了一个全面的分析的各种故障的影响的FRA签名的Transformer的高频模型模拟。通过改变模型中某些电气元件的值来模拟故障。结果发现，绕组的径向位移改变了整个频率范围内（10 Hz-1 MHz）的FRA签名，而由于轴向位移的变化只发生在200 kHz以上的频率。编制了一个列出各种Transformer故障和FRA签名相关变化的表，可用于制定电力变压器Transformer FRA签名解释的标准代码。
This paper presents a comprehensive analysis of the effects of various faults on the FRA signatures of a transformer simulated by a high-frequency model. The faults were simulated through changes in the values of some of the electrical components in the model. It was found that radial displacement of a winding alters the FRA signature over the entire frequency range (10 Hz-1 MHz), whereas changes due to axial displacement occur only at frequencies above 200 kHz. A Table listing various transformer faults and the associated changes in the FRA signature was compiled and could be used in the formulation of standard codes for power transformer FRA signature interpretation.
