| Abstract: | A numerical model for computing the current field in a vertical three layer earth structure is presented in this paper.The formulas for current field computation are deduced via mumerical solution of Laplace equations.With the help of these formulas,we can compute earth resistance by boundary element method,no matter how the conductors may arranged.This calculating method has practical value for designing grounding grids to a large hydropower plant. |
