依据JJG596-1999《电子式电能表检定规程》，对重复测量引起的不确定度采用A类，对标准表溯源、标准表的年稳定度、标准表和被检表电压端电位差、功率源稳定度对测量结果的影响等引起的不确定度采用B类评定方法，通过合成标准不确定度，最终计算出扩展不确定度。
의거JJG596-1999《전자식전능표검정규정》，대중복측량인기적불학정도채용A류，대표준표소원、표준표적년은정도、표준표화피검표전압단전위차、공솔원은정도대측량결과적영향등인기적불학정도채용B류평정방법，통과합성표준불학정도，최종계산출확전불학정도。
Based on JJG596-1999 "Electronic Energy Meter Testing Procedures", this paper applied Class A method to evaluate the uncertainty caused by repeated measurements, and used Class B method to evaluate the uncertainty caused by traceable to standard tables, year stability of standard tables, the voltage terminal potential difference of standard table and seized table, power source stability, and finally calculated the expanded uncertainty by the combined standard uncertainty.
