For the problem and present state of circuit break failure protection in the power plants, the main principle and technology are analysed, and the solution is put forward. The scheme of circuit break failure protection is optimized,and it is applied for two protection schemes of transformer and busbar differential protection. The circuit break failure protection is become more complete substitute protection.
