Normal Earthing, on the other hand, relies on a simple metal rod or plate buried in the earth to create a path for electrical discharges. The effectiveness of normal earthing depends largely on the soil's natural conductivity and moisture content, which can fluctuate over time, potentially leading to higher resistance and lower efficiency. Overall, chemical earthing offers improved safety and longevity compared to normal earthing.
