| Abstract: | The probability of turn--to-turn faults in stator winding is discussed from the point of view of design andmanufacture of large turbo-generator. The necessity and importance of turn--to--turn fault protection for stator winding arepresented. It is pointed out that it is not impossible to connect to six neutral points from generator frame and the constructionscheme with six neutral terminals is designed. Finally, the authors present suggestions on related problems to make up thenew type protection relay for turn--to--turn fault in stator winding. |
