Two transformers connected in parallel share load in the ratio of their KVA ratings, provided their ohmic impedance are
- A. Equal
- B. In direct ratio of their ratings
- C. In inverse ratio of their ratings
- D. Purely reactive
Answer: B. In direct ratio of their ratings
Explanation: For parallel transformers to share load proportional to their ratings without circulating currents, their per-unit impedances on their own ratings must be equal (load shared in direct ratio of ratings).
