“…Then, utilizing COMSOL and computational finite element analysis, the simulation method was used to compare the research study's findings [13]. The results of measuring pH, resistance value and rod length were used to calculate the resistivity value using the Driven Rod Method [14], on Podzolic soil types (Graveled yellow clay) [4], following table of measurement results :…”

It is important to undertake research at the location of PT. Perta Samtan Gas Field Extraction Plant Prabumulih with Podzolik soil type (yellow gravel clay) and analysis in order to prevent work accidents and the risk of fire caused by leakage current at the gas processing extraction installation. Direct measurement of soil resistance value is used as the basis for the methodology, which is followed by literature study as background information and technical comprehension of experimental research. The outcomes of the research study are then compared using Comsol simulation with the computational method of computational finite element analysis of the resulting resistance. According to the data, the resistivity of the podzolic soil was 214.4 Ωm, while the Comsol simulation yielded a resistance value per meter of 209.1 Ω and 196.7Ω, respectively. The Comsol simulation demonstrates that, in order to obtain a ground resistance value of 1 ohm on a Single rod system with Fe material, it is necessary to optimize the depth of the grounding electrode, which can range from 3 meters to 1053 meters d. In the simulation, the results of soil resistance measurements and the Comsol Multiphysics application are obtained, and the difference is calculated with a percentage error of 1.62%.

“…9 Earthing is an act of connecting a part of an electrical or electronic system or installation to the general mass of the earth. [10][11][12] Conductive materials, electrical or electronic circuit, and the general mass of the earth are connected either deliberately by nature or accident through capacitive or inductive coupling. 13 Research has found that by connecting one point in each electrical circuit to a common point of reference (the earth), the difference of potential between electrical systems could be controlled to make electrical appliance and systems safe.…”

Before the introduction of the Ghana Electrical Wiring Regulations 2012 (L.I. 2008), most residential wiring within Sunyani Municipality was carried out by unlicensed artisans. This situation imposed a need to investigate the effectiveness of the earthing systems carried in the Sunyani municipality. Therefore, the current study sought to evaluate earthing resistance effectiveness within the Sunyani Municipality by measuring the earthing resistance of 1004 homes with an earthing resistance tester from January 2016 to April 2018. Again, we predict future resistance based on measured values. Out of 1004 buildings surveyed, 834 had an earthing system in place. Twenty‐eight buildings, recorded an earth electrode test within 0.0 to 10 Ω representing 3.36%. A high percentage (96.64%) had their earth electrode resistance above the acceptable value by the Energy Commission of Ghana. The results revealed that the overall effectiveness of earthing in the domestic installation in Sunyani Municipality is below average compared with Ghana Energy Commission benchmark.

“…Grounding impedance is mainly represented by the resistance of electrodes, the mass of the soil, and the contact resistance between the electrode and the soil [16]. The soil's electrical and magnetic properties under fast transient conditions such as lightning strikes can be explained by three parameters: electrical conductivity, magnetic permeability, and dielectric permittivity [17]. Soil behavior varies under electromagnetic fields due to the different parameters comprising its structure, such as grain size, moisture, salt content, lattice arrangement, and temperature [18][19][20].…”

Application of Mineral Compounds for a High-Voltage Portable Grounding System: An Experimental Study

Electrical grounding is an indispensable part of the power system network. The grounding system is mainly affected by grounding resistance and the nature of the soil. High ground resistance produces the phenomenon of soil ionization, surface arching, and back flashover. A conventional grounding system requires the deep digging of electrodes, thus creating maintenance difficulties. This research work focuses on the safe operation of an electric power system from external and internal impulses arising due to lightning strikes or short circuits. The study proposes an application of mineral samples as grounding materials, and bentonite is used as backfilling material in portable grounding systems. A detailed experimental analysis was conducted under controlled conditions to evaluate the performance of selected materials in high-resistance soil. The problem of a deeply driven electrode is addressed by designing the portable grounding system. The study results demonstrate that the proposed portable grounding system could be installed in troubled environments such as forests, deserts, and rocky terrains. To measure the breakdown voltages of the proposed samples, X-ray Diffraction (XRD) analysis and other laboratory tests were conducted. The electric field intensities are extracted through Finite Element Analysis (FEA). The experimental and simulation findings show the expected performance of mineral samples under various operating conditions. The findings of this study can guide the practitioners for safe and efficient operations of portable electrical grounding systems.
