摘要：
As the large grounding grid occupies large area, the potential difference on the grounding grid is obvious, and the proportion of inductive components in the grounding impedance is larger. Then the design and the operation of the grounding grid are different from the small grounding grid. The paper studies the characteristics of resistive component and inductive component in the grounding impedance of the large grounding grid. The factors affecting the grounding impedance and the features of the large grounding grid are discussed. The results can provide a technical reference for design, operation and maintenance of the large grounding grid.
