🔍 Key Concepts

• Ground fault current in high-voltage AC systems • Difference between solidly grounded, resistance grounded, and ungrounded neutrals • How fault current magnitude affects equipment damage and personnel safety

💭 Think About

• If you connect the generator neutral directly (solidly) to the hull with no resistor, what happens to the size of a ground fault current? • If you completely isolate the neutral from the hull, what happens when a ground fault occurs—do you get zero current, or something else? • Why would engineers choose to add resistance in that path instead of a direct connection or complete isolation?

✅ Before You Answer

• Decide whether the resistor makes fault current bigger or smaller compared to a solidly grounded system • Ask whether any practical system can completely eliminate ground fault current • Consider whether the main function is safety (limiting damage and touch voltage) or just avoiding nuisance trips
