摘　　要：文章通过一个变电站改造的实例,说明地网改造中应对地网的各个参数进行全面校验,包括接地电阻、跨步电位差、接触电位差和计及腐蚀后的热稳定校验,同时应严格控制施工质量。Taking a reformation project of a substation as an example, the authors explain that all the parameters of grounding grid, such as grounding resistance, step potential difference, contacting potential difference, and heat stability after corrosion, should be measured and tested. Moreover, the construction quality should be strictly controlled.
