| Abstract: | In order to improve the correct operation rate of breaker failure protection,this paper,associated with actual conditions of Hebei Southern Grid,discusses the commonly existed problems involving breaker failure protection,such as the logic relation between breaker failure protection and I&C protection,that between transformer gas protection and breaker failure protection,and the three phase operated breaker failure protection.Suggestions to solve these problems are proposed. |
