电能质量分析仪谐波检测结果的不确定度分析

Uncertainty Analysis of the Harmonic Components Measurement of the Electric Power Quality Analyzer

随着法制计量体制的不断发展,电能质量分析仪的检测越来越重要。文章根据实验室认可的要求和计量要求进行了电能质量分析仪不确定度分析,通过重复性测量与稳定性考核等实验得到的数据,证明使用的电能质量分析仪符合电能质量测试的能力要求。

As the development of legal gage control system,the gauging of electric power quality analyzer is more and more important. According to the requirement from the CNAS and power metering,this paper give an analysis on the uncertainty of the power quality analyzer. The analysis validates through repeated measurement and stability assessment that the analyzer can meet the requirement about the ability for electric power quality measurement.
