摘要
目前水轮发电机尚没有所谓的"电位外移"测试方法和标准,本文通过介绍消除瑞丽江一级电站6号机绕组泄漏电流不平衡现象的过程,为以后解决水轮发电机定子绕组三相泄漏电流不平衡或者偏大问题提供了参考。
So far, there is no test method and standard for the so-called＂potential movement method＂for hydrogenerator. The paper introduces the course of eliminating the imbalanced leakage current of No6 generator in Ruilijiang station. It provides reference for solving three phase leakage current imbalance in the future.
