| Abstract: | In 110kV grid, neutral zero sequence protection and clearance protection based on zero sequence current transformer and the clearance of current transformer is widely used for the protection of main transformer neutral point. This paper analyzes the two faults and the principle of protection and the realization process, and discusses the feasibility of canceling the independent clearance. |
