The internal generated voltage EA of a 2-pole, delta-connected, 60 Hz, three-phase synchronous generator is 14.4 kV, and the terminal voltage VT is 12.8 kV. The synchronous reactance of this machine is 4 ohm, and the armature resistance can be ignored.

The answer is given as: enter image description here

However, I do not understand why this is correct. Shouldn't VΦ be equal to VT/√3 = 12800/√3?

VΦ = VT because it's delta-connected.
