Two transformers operating in parallel will share the load depending upon their ?

  • A. Ratings.
  • B. Leakage reactance.
  • C. Efficiency.
  • D. Per unit impendence.

Answer: D. Per unit impendence.

Explanation: Parallel transformers share load in proportion to rating only if their per-unit impedances are equal; otherwise sharing depends on per-unit impedance.
