【摘要】 风电场升压站的地表电位梯度是用来表征接地装置运行情况的重要参数之一，测量风电场升压站地表电位梯度能够为接地电网是否正常可靠运行提供科学、客观和准确的判断依据。文章利用接地阻抗测试仪（HMDWR-5A）对包头市陵翔吉乐图风电场升压站场区的电位梯度进行测量，通过分析测试结果判断其地网接地状况是否理想，并针对测试过程中应注意的用电设备的稳定操作和安全问题进行了总结，以期在今后地表电位梯度检测工作中提供依据和参考。更多还原

【Abstract】 The surface Potential gradient of the transformer substation is one of the important parameters used to characterize the operation of the grounding device. The surface Potential gradient of the transformer substation Measuring can provide a scientific and objective judgment basis for the normal and reliable operation of the grounding grid. In this paper, HMDWR-5A grounding impedance tester is used to measure the Potential gradient of the transformer substation of Lingxiang Jiletu wind farm in Baotou, by analyzing the test results to judge whether the grounding condition of the ground grid is ideal, and summarizes the stable operation and safety problems of electrical equipment that should be noted in the test process, in order to provide the basis and reference in the future surface potential gradient detection work.更多还原
