Therefore, in the process of building electrical engineering construction, how to choose an effective leakage protection technology to ensure the stable operation of the entire engineering system is a problem that the relevant personnel need to think and solve. From the operation and management of the whole project, the application of leakage protection technology in building electrical engineering eliminates and solves the problems existing in the operation of electrical system in time, and creates an ideal environment for building electrical construction. In order to better ensure the safety and stable operation of building electrical system, this paper explores the specific application of leakage protection technology in building electrical construction.展开更多
