Research on the Integral Metrological Performance of Evaluation Method of Smart Electricity Meters

Smart electricity meters are the data bases of monitoring, auditing, counting and analyzing of energy. The verification qualification rate of every single meter can be 99.99% with the fast development of electricity technology, but the risk of error drift still exists in using process. In this article we analyzed the evaluation method of metrological error of smart meters and evaluated the integral metrological level of a smart electricity meters.
