用频率响应法检测变压器绕组的变形

Monitoring the Destortion of Transformer Winding Using Frequency Response Method

论述了频率响应法用于变压器绕组变形测试的全过程,其中包括频响法的原理、检测过程中扫频范围和扫描点数的选取、结果的影响因素和分析判断。最后介绍了用该方法进行年检的测试实例。

The paper introduces a complete procedure using frequency response method to test the distortion of transformer's winding, including the principle, the determination of frequency, range, testing points, and criteria. A practical example is given in this paper, too.
