| Abstract: | This paper analyzes the reasons of low working-rate of breaker failure protection, Several problems are discussed, The feasibility and universality of the voltage blocking releasing approach are explained, which uses the AND logic of protection action and existence information of breaker current. The no-current criterion is suggested to be applied to the setting and logic of failure current judgement element. |
