Introduction At any site selected for the construction of a substation, in general the earth is composed of several layers of soil; but in the design phase, the earth is usually represented by a one- or two-layer model. The two-layer model is a slightly better representation of the natural site, but it complicates the computations considerably, because the two-layer model generates an infinite number of images of the grid conductors that become weaker with increasing value of the z coordinate. This method was inspired by the well-known fact that an object placed between two mirrors generates an infinite number of images. But Huygens, Fresnel,…
