| Abstract: | With the operation of generator differntial protection analyzed, the testing data of the faut recorder and the current transformer is obtained,the possibility of generator fault is ruled out,and the reasons of generator differential protection's operation at the current transformer fault are also illustrated. Some corresponding preventive measures are put forward in this paper. |
