A comprehensive and accurate evaluation of the status of the electricity meter will help guide the actual maintenance work and reduce the waste of resources. In this paper, based on the double entropy correction index weighting, a status evaluation method of electricity meter is proposed. Firstly, according to the principle of index establishment, a relatively complete evaluation index system of electricity meter status is sorted out and constructed. Secondly, the traditional entropy method has been improved, and a method to determine the index weighting based on the double entropy is given, which takes both the subjective experience and objective regularity of the evaluation index into account. Then, a status evaluation model of electricity meters is proposed and applied in a provincial power grid, and the status characteristics of electricity meters of different categories and batches are preliminarily analyzed. Compared with traditional evaluation methods, the effectiveness and superiority of the proposed method are highlighted. Finally, combined with the field experience and the status evaluation results of the electricity meter, a flexible inspection strategy of the electricity meter is given, which can reduce the consumption of material and manpower.
