摘要：
A large number of grounding grids in substations have shapes other than a square or a rectangle, whereas the formulas and graphs for the ground resistance of a grounding grid available in the literature are applicable only to nearly square or rectangular grids. A new simple equation for the estimation of ground resistance applicable to any practical shape of the grid is presented in the paper. The results obtained with this equation have been compared with the accurate results obtained from the computer and the results of the analog model tests.
