摘要
变电站接地系统设计需要可靠和准确的土壤电阻率值,而温纳四极法在土壤电阻率测量中操作方便、准确可靠。从工程实践角度对测量要求、测量方法和测量过程进行阐述,介绍了温纳四极法在变电站工程建设前期土壤电阻率测试中的应用,并对实测数据加以分析,提出减小测量误差的建议。
The design of grounding system of substation requires a reliable and accurate soil resistivity value,while the Winner four-electrode method is convenient,accurate and reliable in soil resistivity measurement.The application of Wenner four-electrode method for an actual substation project construction was introduced through the detailed description of measuring requirements,methods and process.The actual measured data was analyzed,and some suggestions for reducing the measurement error were provided.
