Hi Don,
Isn't the lower voltage ratings - 7200 and 14400- the "phase-to-ground" rating
and the higher voltage ratings - 12470 and 24940- the "phase-to-phase" rating?

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.

Mine has two LV coils but only one HV coil:

    This transformer can be used in 4 different primary distribution
system, 7200V phase to phase & 12470V phase to ground both on switch
position 1 on switch position 2 14400V phase to phase & 24940V phase to
ground.
