“…where: is the effective conductivity, in siemens per meter (S/m) is the effective resistivity, in ohm meter (Ω.m) As shown in Figure 1, Nano-Tech earthing systems for electrical power substations has been explained the distribution of nanoparticles inside the soil medium of electrodes grounding systems and grids grounding systems respectively. In case of Electrodes nanotechnology grounding system the calculation of ground resistance is being as (7)(8)(9).…”

“…In case of a prospective fault current, step voltage, touch voltages and earth potential rise are kept below a safe limit. Thus, this may occur a change in soil characteristics (moisture, pH, and organics), corrosion, accelerated aging from lightning and earth current [6][7][8][9][10][11][12]. As a novel solution to these problems, nanotechnology soil has aimed to both increase soil conductivity and reduce corrosion.…”

The earthing system is very important to safe human’s lives and protect power system from normal and abnormal faults. High soil resistivity regions is the main problem of installation the earthing systems in electric power substations to pass the current through the earth's surface. This paper has been overcome on high soil resistivity regions by penetrating conductive nanoparticles to have extremely low grounding resistance. Moreover, it has been succeeded to examine the methodology of the proposed Nano-Tech earthing systems in case of single rods, multiple rods and grids. Also, it has been defined optimal types and concentrations of nanoparticles for Nano-Tech grounding system to provide excellence protection for electrical substations with respect to built beneath of soil where substation is located. A comparative study has been discussed and analyzed the results of traditional and nanotechnology grounding systems.
