i Have 1000kva 11/.4 kv voltemp make t/f Its a 2 year old. i
wants to known how much iron losses & copper loses during no
load condition.

Answer Posted / er. saumya sucharit senapati

If the transformer is old than with out testing it we can't
say the loss, becuase with time detoriation of metal
occours there fore core and copper losses increases. to
know the losses we have to arrange open circuit and short
circuit tests.
