The information integration system in the master dispatching station of the power grid will contain the condition monitoring contents of secondary equipment in the near future. According to the running condition of the secondary equipment operating in the stations in the current stage and the development tendency of the intelligent secondary equipment in the future

this paper describes the types and status of the secondary equipment

and summarizes the specific contents of condition monitoring of the secondary equipment system. The method for secondary equipment condition monitoring based on power consumption data of secondary equipment is proposed

as is the method for the relevant monitoring based on multi-source related data. Finally

application suggestions for the secondary equipment condition monitoring data are summed up according to the requirements of the master station.
