For the fault at the terminals of a synchronous generator, the fault current is maximum for a
- A. 3-phase fault
- B. 3-phase to ground fault
- C. Line-to-ground fault
- D. Line-to-line fault
Answer: C. Line-to-ground fault
Explanation: At generator terminals X0 is small, so the single line-to-ground fault current can exceed the 3-phase fault current. Verify against the key.
