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
Even thou the diagram dos not show two primary coils the name plate dos
 show SW POS 1 7200 and SW POS 2 14400.
 On the side of the can there will be a switch could look like a pointer
 4" long pointed on one end and a screw in the middle you have to back
out to rotate the pointer 90 deg the other type will look like a knob
about 3" across with a hole in the middle unscrew this knob turn it over
 and the hole in the middle will fit a switch under the knob.

Does yours have a diagram showing this, or simply a
description? Mine does 14.4 and 7.2 kV so two diagrams
for the LV side.

Two diagrams for the LV side show  series and parallel you have to
remove the lid to make this change.

This is a subtractive polarity transformer X 1,2,3 left to right
additive polarity would be X 3,2,1 left to right. To test for Polarity
jumper H1 to the left X bushing put 240V across H1 and H2 now read volts
 across H2 and right X bushing if you get 264V it is additive if you get
 216V it is subtractive.
