发电机转子交流阻抗试验的影响因素分析与应用

The impact analysis and application on the generator rotor AC impedance test

发电机转子交流阻抗试验是判断转子绕组有元匝间短路的实用方法之一，试验方法简单、费用较低、灵敏度较高，多年来被广泛应用。但因其影响因素过多，在试验中容易产生数据误差，造成对绕组匝闻绝缘状况的误判，因此技术人员应对其影响因素充分认识并掌握。

The generator rotor AC impedance test is one of simple method to judge whether the rotor interturn short. The test is a simple and effective way,lower cost and higher sensitive, had been applied extensively for many years. But because its impact factor is too much, easy to produce data error in the tests, cause a misjudgement of winding intertum insulation condition. Therefore the technician should have a full realization and grasp of its impact factor.
