How does grounding differ between AC and DC systems?

• A. The methods of grounding are completely different
• B. The principles are similar, but configurations may vary
• C. DC systems require more grounding than AC systems
• D. AC systems do not require grounding

Answer: (B)

Grounding in AC and DC systems shares fundamental principles such as the objective of enhancing safety and preventing electrical shock or equipment damage. However, the configurations and methods used for grounding may indeed vary between the two systems due to the different characteristics of AC and DC electricity. For instance, in AC systems, grounding methods often involve grounding conductors that connect to the earth and are typically tied to the neutral point of the system. This is crucial for maintaining a stable reference point for the system voltage and minimizing the risk of electric shock. On the other hand, DC systems may utilize different grounding configurations, especially because DC does not alternate direction like AC. This leads to specific considerations, such as ensuring that any grounding path is able to handle the continuous flow of current without creating a hazardous situation. Therefore, while the overarching principles of grounding—such as promoting safety and preventing faults—are similar across AC and DC systems, the actual implementation and configuration can differ substantially.
