why transformer ratings in kva?
Answer Posted / aryan
Since transformer is a static there will not be any
rotational losses it have only iron loss depend upon
voltage and copper loss depend upon current
for AC supply systems like generator, transformer rating is
done in KVA because of inductance present in AC . we don't
know load is resitive or inductive
it is independent there fore it is measured in kva
