摘　　要：为了弥补DL/T621—1997《交流电气装置的接地》所推荐“地网最大接触电位差公式”不适用面积小于30 m×30 m小型地网的缺点,提出了以方环为基本几何模型的地网最大接触电位差新公式,它既适用于小型地网,又适用于大型地网。In order to make up the shortcoming that the ＂formula of the maximum contact potential difference of the ground network＂ recom- mended by DL/T621 - 1997 （（Grounding of AC electrical apparatus）） does not suit to the ground networks of areas smaller than 30 m ×30 m the author puts forward a new formula of the maximum contact potential difference for the ground networks based on the basic geometric model of square circle, which is suitable for both small and large ground networks.
