Using Copper-Coated Round Rod Electrodes at Various Depths in Freshwater Marshes

Published: Dec 7, 2022


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.
