ground grid, mathematical model, three-layer geoelectric structureAbstract
In the paper, factors having effect on computation accuracy of ground grid rated parameters are analyzed. Directions and techniques for increasing the rated parameter computation accuracy are suggested. The techniques consist in improvement of both experimental and computational stages of electromagnetic diagnostics of the ground system condition.
