What is the main purpose of grounding in electrical systems?

The main purpose of grounding in electrical systems is to ensure safety and prevent electrical shock. Grounding provides a safe path for excess electricity, such as during a fault condition or lightning strike, to dissipate safely into the earth. This helps to protect both equipment and individuals from the dangerous effects of electric shock and minimizes the risk of electrical fires.

While providing a reference point for voltage and improving signal quality are important aspects of electrical systems, they are secondary benefits of a proper grounding system. Grounding does help stabilize voltage levels which can contribute to signal integrity, but the primary goal remains focused on safety. Ensuring that electrical systems are properly grounded is crucial in minimizing hazards and protecting both people and property from electrical faults.
