CALCULATION OF RESISTIVITY Based Based on on the the above above tests tests and and according according to to the the recorded recorded values values of of the the resistance resistance against against the the separation of the spikes and the the depth depth of of the the spikes; spikes; soil soil resistivity resistivity isis calcula calculated as follows:

(Equation Equation 49 4 9 from IEEE 80-20 80 2013 13)

Where; Rm

=

the apparent soil resistivity at a depth of ‘b ‘ b’’ in Ωm.

However, assuming assuming that that the the tests tests were were carried carried out out in in homogeneous homogeneous soil soil and and that that the the depth depth ““ b However, b”” (which is the depth of the test spikes defined by a/10) a/10) is small compared to “a”; which is the case probes penetrating penetrating the the ground ground isis only only at at a a short short distance; distance; then then present at our joint locations as the probes the soil resistivity is simplified to:
