| Abstract: | In order to find the fault of unbalanced current when 150MW hydro-generator stator windings leak in Letan power plant,the paper discusses the test on insulation condition of the end of stators of hydro-generator set and analyzes the causes of deficiency and treatment process,which sheds light on finding why hydro-generator stator windings leak and its treatment.After replacing the terminal box of the generator,the author finds that all of the test items of the generator are up to relevant requirements. |
