摘　　要：校准不确定度能够全面说明计量设备校准能力的优劣,成为考核电能计量标准装置综合性能的重要依据,文中以实例给出0.002S级双级电流互感器不确定度评定方法及其验证方法,评定结果给出了校准不确定度的可靠程度,为电流互感器的校准工作提供参考。Measure uncertainty is an important factor in verifying the general capability standard electric energy equipment. At the pres-ent, there is little research on the uncertainty of the two-stage current transformer. In this paper, the evaluation method and the verifi-cation method of the uncertainty for the 0.002S two-stage current transformer are proposed as an example. The reliability of calibrationuncertainty is confirmed by the results of evaluation.
