The reason for this is historical. Before rev 27 branches and transformers belonged to the same data group, i.e. a transformer was a special branch with a ratio at one end.

Check "abrncplx" with string "RX" to get complex-formatted branch impedance values. Use python (.real and .imag) on the complex value to get its components.
