In order to realize the temperature detection for high voltage equipments in power plants

a wireless temperature measurement system is designed. The system is extended to the remote end and the mobile terminal system is designed to overcome the limitations of in situ monitoring. The design of this wireless temperature measurement system is based on wireless sensor network(WSN)

and the mobile terminal design is based on Android system. The system takes cloud server as the center and uses the 3 G/4 G network

which can realize real-time data monitoring in period of 2 s. The actual detection shows this wireless temperature measurement system runs well and the mobile terminal system is stable

which has good scalability and portability. The system has been successfully applied in the 500 k V main transformer temperature measurement system.
