In view of such problems as low efficiency and weak reliability of the state monitoring and fault diagnosis system in traditional energy metering device

the state monitoring and diagnosis system of electric energy metering system based on cloud storage platform is developed in this paper.The system combines the running state data of the extra-high voltage electric energy metering device and cloud computing technology to realize the online real-time monitoring and management of the metering device.The early warning and diagnosis for the fault of the device are performed in advance through remote data collection

storage and fusion processing of the device and the development of pre-processing and data analysis module.The experimental results show that the designed system can compared to the fault diagnosis method of traditional energy metering device

monitor

pre-warn and diagnose the state of the electric energy metering device timely and comprehensively and provide reliable and effective operation and maintenance data support for the metering device.
