| Abstract: | The paper has carried on related research on the interval transformer protection＇s failure in double busbar connection. Principle and characteristics of the bus protection are discussed in this paper. The importance of bus protection and the configuration principle of busbar differential protection are also given. In addition, the paper analyzes the relationship between the busbar protection and transformer interface. Finally, combining with the practical problems, this paper puts forward different processing methods of the interval transformer protection＇s failure in double busbar connection, and analyzes the basic situation of each scheme. |
