本文介绍了在北威尔士Dinorwig抽水蓄能电站建立一个大型室外实验设施，以研究实际接地系统的性能。描述了设备本身以及测试电极和测量设备的安排，为后续测试方法提供了背景。此外，还进行了测试，以确定水和储层电阻率的变化，从而获得了一组调查数据，可以更好地为实验工作和垂直地棒和网格电极的模拟提供信息。有人建议，该设施也可用于校准接地仪表和验证计算建模技术。在一篇补充论文中，描述了不同量级的低压直流、交流和脉冲试验的结果，并将实验结果与数值模型的计算值进行了比较。
This paper describes the establishment of a large-area outdoor experimental facility at the Dinorwig pumped-storage power station in North Wales for investigating the performance of practical grounding systems. The facility itself and arrangements of test electrodes and measurement equipment are described, providing a background for subsequent test methodologies. In addition, tests to determine the variation in the water and reservoir bed resistivities have been undertaken, resulting in a survey data set that better informs experimental work and simulations of vertical ground rod and grid electrodes. It is proposed that this facility may also be used to calibrate grounding meters and for validating computational modelling techniques. In a complementary paper, results of low-voltage dc, ac, and impulse tests of varying magnitudes are described, and experimental results are compared with computed values obtained from numerical models.
