A transformer bank is made up of three single-phase transformers
rated 240/360/400MVA, 500kV wye-grounded / 24kV delta. The
impedance of each transformer is 12.3% on base MVA.
a. What is the impedance of the transformer bank in per-unit on
100MVA?
b. What is the impedance of the transformer bank in 500kV
