The primary purpose of the ground rod is to provide an electrical connection between an electrical system and the Earth’s ground, ensuring safety and proper functioning of the system. Materials. A grounding rod made of pure and solid copper in the form of a copper rod is the preferred choice for grounding and earthing systems.
Accurate design of a grounding system requires an accurate assessment of the site’s soil conditions. However, even a small site will often have widely varying soil resistivity from one spot to another.
Prioritizing high-performance design reduces environmental impact, enhances operational efficiency, and ensures long-term resilience in serving the community’s emergency response needs.
