In view of the quality monitoring problem in the operation of the automatic verification device for electricity meters, based on the analysis of the design structure, working process and existing monitoring methods of the automatic verification device for electricity meters, and according to the principles of simplicity, efficiency, convenience and reliability, this paper proposes a novel online automatic monitoring method for the operation status of the automatic verification device for electricity meters. This method adopts a high-precision installed standard electricity meter to carry out online automatic detection and periodic verification of the automatic verification device of electricity meters in operation, establishes a data analysis model, realizes real-time analysis of test data, and has been applied to the automatic verification device of electricity meters in the metering center of Yunnan Power Grid Corporation. The results show that the proposed method can effectively monitor the operation quality of the automatic verification device of electricity meters, and provide support and reference for equipment evaluation and data maintenance.
