摘　　要：依据JJG596-2012《电子式交流电能表》[1]和JJF 1117-2010《计量比对》[2]国家计量技术规范,由河南省计量院为主导实验室组织实施了"河南省单相电子式电能表量值比对"的计量比对工作。计量比对能够考察各实验室量值溯源的一致性,同时对实验室计量标准、环境条件、人员的技术能力进行考核和评判。[3]计量比对的测量结果与其不确定度的一致性采用En值进行评判,并对比对中存在问题进行了总结,对下一步开展检定工作具有很好的指导作用。According to JJG596-2012 " Electronic Alternating Current Energy Meter" [1]and JJF 1117-2010 "Measurement Comparison" [2]National Metrology Technical Specification,Henan Institute of Metrology as the leading laboratory organized the implementation of " Henan Province single-phase electronic energy meter value comparison" measurement comparison work. Metrological comparison can examine the consistency of traceability of laboratory measurements,and evaluate the measurement standards,environmental conditions and technical ability of laboratories.[3]The consistency between measurement results and uncertainty is evaluated by Envalue,and the existing problems are summarized,which has a good guiding role for the next verification work.
