| Summary: | In order to solve the problem of 8-year expiration replacement of smart electric energy meters, three schemes for electric energy meter replacement are introduced and analyzed. The improvement of the production level of smart energy meters has provided a necessary basis for extending the replacement period of electric energy meters. In view of the scheme of extending the replacement period with field verification method, a correction is made of the operation life process of the electric energy meter based on Weibull distribution analysis considering the climatic factors of different regions and the influence of the field verification result of the electric energy meters. The theoretical analysis and actual application have proved the feasibility of the proposed method, which will provide a reference for extending the replacement period of the smart electric meters. |
