In fact, there will be a rise in the voltage as can be seen in Figure below. This happens when a leading current passes through an inductive reactance (which is the transformer itself).
Preceding phasor diagrams have illustrated the relationship between the various voltages and currents and the phase angles between them for a single-phase transformer.
As you can see:

V2 > E2
