Abstract Leakage protector to prevent electrical fires up the vital role in the protection of human or animal to get an electric shock, in the power grid. As the core component of the RCCB electromagnetic tripping device (EMR) whether reliable action is directly related to the reliability of RCD. Electromagnetic release this paper to test failure(EMR) began, find out the causes of EMR failure, and put forward the improvementscheme, through the feasibility test plan, in order to improve the reliability of the protector.
