Abstract
The Authors suggest a new method for quickly determining the maximum touch voltage generated by a grounding system leaking a known current. The touch voltages in the points of the soil surface are calculated by the Maxwell’s subareas method and the search for the maximum touch voltage is carried out by an ad hoc genetic program which is based both on the “one-point crossover” technique and on a mutation having a pre-arranged probability rate. The method has been successfully tested on some grounding systems.
