What should be done if soil resistivity is too high at a site?

High soil resistivity can significantly impact the effectiveness of grounding systems, as it creates a higher resistance path for fault current. When the soil resistivity is too high, it can lead to inadequate grounding, which may compromise safety and system reliability.

Utilizing additional grounding electrodes or ground-enhancing chemicals is a practical solution to this problem. Additional electrodes can provide multiple paths for fault current to dissipate into the earth, effectively reducing overall resistance. Ground-enhancing chemicals can help to lower the resistivity of the soil, improving electrical conductivity and the performance of the grounding system.

This proactive approach ensures that grounding systems function properly, offering sufficient protection against electrical faults and reducing the risk of shock hazards or equipment damage, which are critical considerations in electrical installations.
