WebOct 1, 2024 · For example, Dawalibi [5] determined the effect of earth resistance to earth value of an earthing grid design for a substation constructed on a two layered soil type. In another work, Dawalibi and Barbeito [6] showed that a uniform soil layer could be implemented for resistance to earth calculation for a two layered and multi layered soil type. WebThe earth rods would stabilise the earth grid resistance over seasonal resistivity changes at the grid burial depth. 1.7 Substation Fences The earthing of metallic fences around a substation is of vital importance because dangerous touch potentials can be involved and the fence is often accessible to the general public.
