测量不确定度评定方法在10 kV配电线路杆塔接地电阻测量中的应用与分析

Application and Analysis of Measurement Uncertainty Evaluation Method for Grounding Resistance Measurement of 10 kV Distribution Line Tower

对配电线路杆塔的接地电阻测量结果进行了不确定度的评定和分析。通过对重复性测量结果的比较,分析了影响测量结果的A类不确定度和B类不确定度。结合桂林地区10 kV配电线路的接地电阻测量,讨论了测量不确定度的来源,介绍了评定不确定度的方法,并评定和分析了测量结果的不确定度。

According to the grounding resistance measurement of the distribution line tower,the uncertainty of measurement results was evaluated and analyzed.By comparing the repeated measurement results,the class A uncertainty and class B uncertainty which affect the measurement results,were analyzed combined with the grounding resistance measurement of 10 kV distribution line in Guilin,the source of measurement uncertainty was discussed.The methods of evaluating uncertainty was introduced,and the measurement uncertainty was evaluated.
