| Abstract: | According to the characteristics of autotransformer, the fault current of autotransformer is analyzed when the ground fault happens in and outside of the protected zone. The advantages and disadvantages of three kinds of zero-sequence current differential protections of autotransformer are discussed and some suggestions are given . This paper has something important to improve the application and sensitivity of zero-sequence current differential protection of autotransformer. |
