What is the order of sequence of impedance in salient pole alternator?
- A. Z1 > Z2 > Z0
- B. Z1 < Z2 < Z0
- C. Z0 > Z1 > Z2
- D. None of the above
Answer: A. Z1 > Z2 > Z0
Explanation: In a salient-pole synchronous generator, positive sequence impedance Z1 is largest, negative sequence Z2 is intermediate, and zero sequence impedance Z0 is smallest: Z1 > Z2 > Z0.
