Introduction

The grounding system, also known as a lightning rod, is a crucial component in the electrical system that aims to ensure the safety of equipment and the surrounding environment. Its primary function is to drain excess current or voltage that can endanger electrical equipment and living things around. According to the PUIL 2007 standards, the ideal soil resistance value for the grounding system is less than 5 ohms, and less than 3 ohms for the electronic device frame. Various factors affect the value of soil resistance, such as soil resistivity, soil humidity, mineral content, and soil temperature.

In this study, we aim to analyze the effect of the use of bentonite cement on stem electrodes by doing variations on the diameter of the bentonite media used. The use of bentonite cement has specific properties that can affect electrical resistance. By understanding the impact of bentonite cement on stem electrodes, we can design a safer and more efficient grounding system that protects electrical equipment and the safety of living things around it.

Research Methodology

This study uses a resistance measurement method with a single stem electrode that is applied using the three-point method. The soil media used is replaced with bentonite cement, which has specific properties that can affect electrical resistance. The measurement results show that the best resistance is produced by the cement media bentonite with a diameter of 25 cm, which has a humidity of 90%, with a resistance value of 13.38 Ω. In comparison, the resistance of the original soil media with a humidity of 50% is 19.24 Ω.

Results and Discussion

The results of the study also included different variations of bentonite diameter. The resistance measured for a diameter of 10 cm, 15 cm, 20 cm, and 25 cm each is 18.53 Ω, 16.63 Ω, and 14.53 Ω. From these observations, it appears that the greater the diameter of the bentonite media, the lower the resistance value. This shows that bentonite has good potential to increase soil conductivity in the grounding system.

Furthermore, the ratio of reducing resistivity value shows significant results. On the third day, the reduction in resistivity for a diameter of 25 cm compared to other diameter variations reached 30.54%. As for the diameter of 10 cm, 15 cm, and 20 cm, the reduction is only 3.78%, 13.64%, and 24.56% respectively.

The Effect of Bentonite Diameter on Resistance Values

The results of this study show that the diameter of the bentonite media has a significant impact on the resistance values. The larger the diameter of the bentonite media, the lower the resistance value. This is because the larger diameter of the bentonite media provides a greater surface area for the flow of electrical current, resulting in a lower resistance value.

Comparison with Original Soil Media

The results of this study also show that the resistance value of the bentonite cement media is lower than that of the original soil media. This is because the bentonite cement media has a higher conductivity than the original soil media. The bentonite cement media has a higher concentration of ions, which allows for the flow of electrical current, resulting in a lower resistance value.

Conclusion

The use of bentonite cement in grounding system applications has proven to be effective in reducing resistance values. Variations in the diameter of the bentonite media also play an important role, where larger diameters tend to produce lower resistance. These findings can be utilized in the design of a safer and more efficient grounding system, so as to protect electrical equipment and the safety of living things around it. Further research can be done to explore a combination of materials and other conditions that can further improve the performance of the grounding system.
