介绍了国内外电力变压器绕组材料鉴别的基本现状，提出了诸多理论可行的材料无损鉴别方法，通过大数据统计、理论分析和试验证实相结合的方法，比对各种方法的优缺点及其可行性。此探讨对电力变压器绕组无损鉴别方法的设备开发和标准制定具有一定的指导意义和工程应用价值。

This paper introduces the basic status quo of material identification of power transformer windings both at home and abroad, puts forward many theoretical and applicable methods of nondestructive identification, and validates the method through the combination of big data statistics, theoretical analysis and experiment verification. Finally, comparisons were made on the advantages and disadvantages and their feasibility. This discussion has certain guiding significance and engineering application value for equipment development and standard setting of nondestructive identification method of power transformer windings.
