Adam,
To obtain the current the equation  I = P x 1000/ V should suffice, where I
is the current in Amps ,P is the power in kVA and V the voltage in volts.

For P= 1.5kVA and V=14000V the current I  (rounded to 3 decimal places) is
0.107 amps

The voltage (in volts) is given by the formula
V = 1000 x P/ I

So for P = 1.5kVA and I =.107A the calculated voltage V ,rounded to three
decimal places, would be 14018.692 volts (nearly 14000 volts plus a bit)

You can check this by multiplying .107 by 14018.692 and dividing by 1000

.107 x 14018.692/1000 =1.5 kVA exactly.
