Abstract With the popularization and perfection of surge protective device（SPD）protection，more and more on-line SPD have been developed，but sufficient importance has not been attached by owners in the safety performance problem of on-line SPD in low-voltage lines that have been installed for years. In this paper，the requirements in the related specifications about safety performance maintenance and detection of on-line SPD are listed；some problems existing in the practical on-line SPD detection process are discussed；a kind of on-line SPD real-time dynamic monitoring and management system is presented；and the configuration of the software and hardware as well as the functions of the system are introduced.
