摘　　要：目前,新型的电子式电能表标准装置均使用宽量限标准电能表,而宽量限标准电能表按传统方法检定其基本量程不能覆盖到标准装置的全部输出量限,因此不能保证输出量限的精确度,针对此问题文章从原理上介绍了普通标准电能表和宽量限标准电能表的区别,通过对几块实例宽量限标准电能表的检定数据的比较,提出了检定宽量限标准电能表时,选择覆盖量限的方法。Original verification method of wide range standard watt - hour meter is not applicable, bot the national measure verification rule doesn ＇ t provide the verification of wide range standard watt - hour meter therefore it ean＇t ensure the precision of output range. The paper introduces distinguish of common standard watt - hour meter and wide range standard watt - hour meter form principle, and points out the verification method of wide range standard watt - hour meter, through comparing with several verificating data of wide range standard watt - hout meters.
