Long-term safe and stable grounding system is the fundamental guarantee to maintain the stable operation of equipment and ensure the safety of staff. This paper investigates the high-frequency characteristics of several common grounding materials. Due to the skin effect, the axial impedance modulus, resistance part and reactance part of the conductor are all increase as the frequency. The results could provide reference and guidance for designing long-term reliable and stable grounding systems.

“…A system or safety installation with a grounding system or usually known as a grounding system, specifically a safety system against devices that employ a grounding system (Camara et al, 2020), can overcome the protection system needed for disturbances, short circuits, disturbances from lightning strikes, or ground disturbances. Electrical surges caused by lightning are the primary source of electricity as a power source (Łukaszewski & Nogal, 2021).…”

Purpose: High-voltage electrical equipment requires a grounding installation in order to protect lives in freshwater swamps with a hydrogen potential of 6.75. To build a grounding structure, it is required to know the resistance value and grounding materials, namely copper-coated rod electrodes at different depths. Research methodology: The research was conducted in a freshwater swamp close to the shampooing substation using field observations and direct measurement of soil resistance values, followed by a literature review and comparisons using COMSOL simulation and FEM Analysis. Results: The results of direct research and simulations indicate that in order to accomplish a grounding resistance value < 5 ohms according to the PUIL 2011 standard for a single rod system made of copper, it is necessary to optimize the depth of the grounding electrode within a range of 10 meters, which differs from the simulation results of ground resistance measurement and the Comsol application. The percentage error is 1.05%. Limitations: This research analyzes the results of measurements and grounding analysis using Comsol Multiphysics at a depth of 1 meter for a particular type of copper-coated round rod electrode at depths of 1, 1.5, and 2 meters. Contributions: The results of the study offer information on the usefulness of grounding resistance in freshwater wetlands with a pH greater than 6, where several rod electrode types are utilized to compare future research.

“…Electrical equipment must be protected from abnormal circumstances, such as exposure to overvoltage or leakage current, using a security system [3]- [4]. The grounding system is designed to transmit electric current to earth under normal conditions and fault conditions [5], without exceeding the operating limits of the equipment or affecting the company's operational continuity processes. Even though the system design has been set as reliable as possible, in the grounding process unavoidable disturbances can occur [5], such as the occurrence of insulation leaks in the Grounding system which causes some systems to trip [3].…”

The amount of corrosiveness (pH and resistivity) has a significant effect in variations in the resistance value in the grounding system, which are induced by chemical and physical changes [6].…”

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%.
