Question: A three-phase transformer is rated 500 M V A , 220 Y / 22 k V 500 M V A , 220 Y /

A three-phase transformer is rated $500 M V A, 220 Y / 22 Δ k V$ . The wye-equivalent short-circuit impedance, considered equal to the leakage reactance, measured on the low-voltage side is $0.1 Ω$ . Compute the per-unit reactance of the transformer. In a system in which the base on the high-voltage side of the transformer is 100 MVA, 230 $k V$ , what value of the per-unit reactance should be used to represent this transformer?
