Augmenting the electrical systems reliability can be accomplished by earthing every stage of electricity generation, transmission and utilization. An accurate grounding system resistance calculations recommend to consider the relevant realistic effective parameters. This paper demonstrates the effect of these parameters such as soil types, soil moisture status in terms of the ambient temperature and finally the earthing electrode types and dimensions. This study comprises the common soil moisture statues such as frosty, cool, wetted, liquid, worm or dries for each of boggy, clay, sandy, silty, peaty, chalky, loamy soils. Moisture proportion varies in these soil types that could lead to diversity of soil resistivity.Full description of earthing resistance profile in case of the different soil types, different environmental conditions as well as different electrode types will be presented. Individual MATLAB files for the different electrodes types will be developed. This work extends the soil moisture states and their effects throughout the whole earthing calculations. The system point by point results are in successfully agreements with the corresponding ETAP results.
