The slot leakage can be calculated by making which of the following assumptions ?
Correct answer: D. All of the above
- A. The current in the slot conductors is uniformly distributed over their cross-section
- B. The leakage path is straight across the slot and around the iron at the bottom
- C. The permanence of air paths is only considered. The reluctance of iron paths is assumed as zero
- D. All of the above
Explanation
Slot-leakage calculations assume uniformly distributed slot current, a simplified straight leakage path, and negligible iron reluctance so that only air-path permeance is considered.
