 ANd here you are:
http://www.geindustrial.com/products/brochures/DEA-271-English.pdf

Look at page 2, Conventional. 14400 primary voltage, 120/240 secondary.
That's probably a 15kV voltage class, so the BIL would 125 kV.
(granted, yours isn't a 100kVA)

http://www.geindustrial.com/products/brochures/JVB-004.pdf is probably more 
your style (residential).  14400 shows 125kV BIL

If your transformer has a nameplate on it (and it should), the BIL rating 
should be on there too.
