The main objective of grounding electrodes is to provide a low-resistance path to the ground for electrical currents. This is crucial in protecting both equipment and personnel from electrical faults. When a fault occurs, such as a short circuit or equipment leakage, having a reliable grounding system ensures that the electrical current has a direct route to the earth. This prevents the build-up of high voltage on the equipment, which could lead to dangerous shocks or equipment damage.

By establishing a low-resistance path, grounding electrodes help to quickly divert unwanted electrical energy away from circuits and safely into the ground, thereby minimizing hazards associated with electrical faults. Grounding systems are essential in maintaining safety standards and protecting both human life and electrical infrastructure.
