Total t/f loss depend on vA copper loses depend on current &irnon loses depend on voltage not on phase angel between &current.it is independent of load power factor thats why t/f is in kva not in kw.hope  u wil be satisfied

Answer / guest

The transformer is designed to supply rated total power to the
load. So its rated in KVA and not in KW

Answer / ali

the transformer total power is sq root of (apparent power)2 + reactive power)2 ... so the apparent power is always in kva and it is also depends upon the current and voltage ratings
