It depends on what power the "LV" winding is drawing, else with 137V in and 290 out KVA = 2000, do the maths to find the current in the 290 -> 240 section, this will give you the wire gauge for this part of the winding and the 137V winding EXCEPT that you don't know how much power is in the LV bit.

i can't understand, pl explan as eqe.
 

hey chuckey why not you design whole project :lol::lol::lol::-D
 

STEP UP
input v 137
output v 240
output w 1200
effi 85


transformed voltamp 515.00

PRIMARY CURRENT 4.4225

SECENDRY CURRENT 5



power 515.00 W Calculated core area 26.14304037 SqCm
toung width 2 Inch
stack height 2 Inch Core area 25.8064 SqCm
Calculated power 501.8222242 W

CORE FLUX 1.3
T/V 1.34
maxvolt 290
normal op volt 240
T/V Multification 1.2
CALCULATED T/V 1.95 = 1.9

make taps at secendery as needed
