摘要(Abstract)：

针对高土壤电阻率的接地网,根据变电站现场实际情况,采取外延接地体、扩大外延接地网、换入低电阻率土壤等综合降阻措施来降低接地电阻,这样既有效又经济,校核了接地电阻偏高接地网的接触电压和跨步电压。
In accordance with grounding grid with high earth resistivity and practical situation of substation,comprehensive measures such as extension of ground body,expansion of extended grounding grid and replacement by low-resistivity earth are taken to lower ground resistance,which is effective and efficient and verifies high grounding resistance,touch voltage and step voltage.
