Bank of 2 - 1425 kV BIL and 1 - 1550 BIL one phase transformers
Bank of 2 - 1425 kV BIL and 1 - 1550 BIL one phase transformers
(OP)
Can somebody tell me if it is feasible in a bank of three, to replace 2 x 65 MVA, one phase, 400 kV units with 1550 kV winding BIL, and keep a third one that is 1425 kV BIL rated? It looks weird that the bank should be split in 2 transformers with 1425 BIL and 1 with 1550 kV wqinding BIL.

Voltage ratio on the selected taps is of course a parameter you need to match very closely.

I would be much more concerned about the impedance. It is important that all three units have matching impedances.
