电缆导体直流电阻能力验证测试过程分析及不确定度的评定

Process Analysis of Proficiency Testing and Measurement Uncertainty in Conductor DC Resistance of Cable

根据电缆导体直流电阻能力验证计划要求,分析、介绍了验证试验所采用的测量原理和验证试验过程,建立了导体直流电阻测量不确定度的数学评价模型。结合测量结果给出合成不确定度,并对该验证试验作了小结。

According to the requirements of proficiency testing scheme of conductor DC resistance of cable, the measurement principles of resistance method and the testing process were analyzed and introduced. A mathematic model was established to assess the measurement uncertainty of conductor DC resistance. Combined with the test results, the model can give the measurement uncertainty , and summarized the testing.
