摘　　要：校准装置的测量不确定度是确保量值传递准确性的重要指标参数,所以测量不确定度的评定方法及过程尤为重要。文章结合DL/T 1028—2006《电能质量测试分析仪检定规程》,介绍一种以电能质量校准器为主标准器的电能质量分析仪远程校准装置的测量不确定度评定方法,以电压和频率参数的校准为例,建立测量不确定度数学模型,分析各参数的不确定度分量来源并进行定量计算。The measurement uncertainty of calibration device is an important parameter for the ensuranceof the accuracy of disseminationof value of quantity,so the evaluation method and process of measurement uncertainty are particularly important.Based on DL/T 1028—2006“Verification Regulation of Power Quality Testing Analyzer”,this paper introduced a measurement uncertainty evaluation method for remote calibration device of power quality analyzer with power quality calibrator as the main standard,es-tablished a mathematical model of measurement uncertainty of parameters such as voltage,current,harmonics,frequency and flickering,analyzed the sources of uncertainty components of each parameter and made quantitative calculation.
