The grounding is the connection of the metal structures of machines with electrical equipment in order to remove the electrical charge from the earth by the grounding through locked connection and to prevent possible damaging of the equipment and the loss of the operator’s life. Thus, any construction will have a risk produced by a fault current or lightning unless has a suitable grounding system. According to the international standards, the agreed grounding resistance should be 1 or lower. The challenge is to get the standard value of grounding resistance under various environmental conditions. Therefore, to manage troubled environments that suffer from high resistivity soil, bentonite substance has been proposed to use for electrical grounding applications in distribution networks to get the lowest value of grounding resistance. Ground network of eight 33/11 kV substations with its conductors are designed then part of the electrode holes are filled by bentonite. The designed T-shape was used in the implementation of the selected substations according to the standard reference IEEE Std. 80-2000/2013. A T-shape is chosen for its economical purpose based on the conductor length utilized compared to other models (rectangular, square and L-shapes). The ground network resistance for each substation was examined and measured at various anchorage points for one month. The resistors’ performance was studied utilizing an earth tester device, and the simulations software was ETAP 16.0.0. Our suggestion shows promising results and a considerable decrease of about 75% for the earthing resistance which contains a certain percentage of the substance. In addition, an acceptable error ratio resulted between the simulation and measured values of earth resistance which opening new prospects for using ETAP in distribution utilities.
