Achievement of the best design for unequally spaced grounding grids

(in lingua inglese)

In this paper two different approaches were used to achieve the best design configuration of grounding grid as increasing sequential multiplication factor (a) or sequential power rule factor (b) leads to better results but that up to certain limit (nearly at a = 1.5 and b = 1.25). After this limit, the results tend to be constant at some cases and tend to increase again at other cases. Generally we can consider the models achieved the best results at (a = 1.5) and (b = 1.25). Selection of a or b depends on the presence of driven rods which in turn improves the grid’s parameters.
