摘　　要：以在用10 kV变压器为测试对象,测量其直流电阻及绝缘电阻,研究其三相不平衡率,配合开展交流耐压试验,分析得到了测量对象的运行状态及潜在故障.Taking the 10 kV transformer in use as the test object, the DC resistance and insulation resistance were measured experimentally.The three-phase unbalance rate was studied, and the AC withstand voltage test was carried out in cooperation.The operation status and potential faults of the measured object were analyzed based on the experiment results.

关 键 词：直流电阻 三相不平衡率 绝缘电阻 交流耐压
