Which method is commonly used for establishing a ground connection?

The method of using ground rods driven into the earth is a widely accepted practice for establishing a ground connection in electrical systems. Ground rods are typically made of conductive materials, such as copper or galvanized steel, and are driven into the ground to create a low-resistance path for electrical faults to safely dissipate into the earth. This grounding method is crucial for preventing electrical shock hazards and ensuring the safe operation of electrical equipment by providing a reliable pathway for fault currents.

By connecting electrical systems and equipment to earth through ground rods, it helps to stabilize voltage levels in the system, minimizes the risk of damage from lightning strikes, and reduces the potential for interference with the normal operation of electrical devices. This established ground connection is essential for maintaining the safety and integrity of electrical installations.
