接地电阻检测的测量不确定度分析

Analysis of Uncertainty in Measurement of Ground Resistance

通过防雷实验室评审和计量认证的过程,分析了接地电阻测量中的不确定度来源,包括检测操作人员素质、检测使用仪器精度、检测环境情况和检测方法的匹配程度等,其中检测方法是综合判断测量不确定度的重点。找出可作为不确定度评定可靠程度的指标后,按其置信概率通过估计法进行接地电阻检测数据精度的处理,对同类研究具有参考价值。

The sources of uncertainty in t of ground resistance were analyzed, including staff quality, accuracy of detection equipment, rationality of the test environment and test methods. Detection Method is the key point of uncertainty in measurement of synthetic judgment. Finally, you can make detection by estimating method of data processing. It could provide references for similar research.
