摘　　要：电力变压器遭受短路冲击后,应尽快判别绕组损坏情况。利用频响分析法、短路阻抗法、绕组电容量法,结合绝缘油色谱分析、绕组直流电阻测试和电压变比测试等试验对一遭受短路冲击后的变压器绕组变形情况进行综合诊断分析。经验证,综合分析结果与实际情况一致。After suffering the impact of short-circuit,the damage of power transformer windings should be judged as soon as possible.In this paper,we take a comprehensive analysis on a transformer winding which has suffered the impact of short-circuit by using frequency response analysis（FRA）,short-circuit impedance method,winding capacitance test combined with the DGA,winding DC resistance test and voltage transformation ratio test,etc.The comprehensive analysis verified the results with the practical situation
