Three single-phase two-winding transformers, each rated 400 MVA, 13.8/199.2 kV, with leakage reactance per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected. The high-voltage windings are connected in Y. A three-phase load operating under balanced positive-sequence conditions on the high-voltage side absorbs 1000 MVA at 0.90 p. f. lagging, with Icon . Determine the voltage at the low-voltage bus if the low-voltage windings are connected
