On the basis of instantaneous forced analysis to short circuit of power transformer and numerical value calculation using low voltage impulse analysis, the paper presents the essentiality of winding distortion after short circuit of power transformer. By contrasting the three main ways of the world such as low-voltage impulse、 short circuit impedance analysis and frequency response analysis , FRA is adopted for distortion testing. Then we design a new testing instrument of transformer winding distortion—testing system of transformer winding distortion.

本文首先在对电力变压器短路时的瞬时受力分析及所受电磁力的有限元法的数值计算的基础上，论证了电力变压器短路以后进行绕组变形测试的必要性；然后通过比较的方法对目前国内外主要使用的三种方法：低压脉冲法、短路阻抗法和频率响应法，进行了一一对比，并根据对比结果，确定在本课题中使用频响法；最后在理论研究的基础上，设计出了一种新型的变压器绕组变形测试仪——电力变压器绕组变形测试系统。

The enzyme spectrum of FMR1 locus also indicates the potential existence of other gene in the region several kb 5'to FMR1 gene, whose inactivation may also be affective in Fra syndrome.
