| Essential Question | Level of Thinking |
| What are the characteristcs of ungrounded, high resistance grounded, and solidly grounded power systems? | |
| What are commond mode voltages and currents, what are the typical common mode voltage sources and common mode impedances found on ships, and what are the implications of common mode currents flowing in the ship's hull? |
|
| What are separately derived systems, how are they implemented, and what are the implications of not operating two power systems as separately derived systems? |
|
| How are ground faults detected, localized, and isolated for the different types of grounding systems? | |
