摘要
通过三个直流电阻异常的实例，综合油色谱和其他电气试验对故障进行了分析诊断，在此基础上总结了电力变压器直流电阻异常的故障诊断思路和方法。
With three examples of abnormal DC resistance, this paper diagnoses the faults by integrating dissolved gas analysis （DGA） and other electrical tests. At last,the method of fault diagnosis for power transformers with abnormal DC resistance has been given.
