Hi David
  Those voltages are all phase to phase system voltages. On 12470 
the phase to ground would be 7200, and on 24940 phase to ground would be 14400.

The left diagram on the name plate shows the secondary in series; A 
to X1, C&B to X2, and D to X3. The right diagram shows the secondary 
in parallel; A&C to X1 and B&D to X2.  Low voltage is 120/240.
