| 摘 要： | 为了避免用传统误差体系的概念表示测量结果可能引起的不足，近年来在国内外科技文献中，讨论测量结果的误差时都已采用了测量不确定度来表示。根据测量不确定度的评定与表示方法，通过对交流电能表检定装置的各项误差源的分析，对交流电能表检定装置的不确定度进行了分析，最后对0．02级三相交流电能表检定装置的不确定度进行评定。

| Abstract: | In order to avoid the lackness of using the concept of traditional error system to express the measurement result,in domestic and international technology materials,the measurement error result were expressed with the concept of the measurement uncertainty recently. According to the evaluation and presenting method of the measurement uncertainty and the analysis of the various error source of the AC electrical energy meter calibration , the uncertainty of AC electrical energy meter calibration was analyzed . Finally the uncertainty grade of 0.02 of three-phase AC electrical energy meter calibration was evaluated. |
