I think Copper loss of a transformer is related to current
and core losses are related to voltage so that VA should be
the rating of a transformer. But in a large transformer it
is rated it KVA. Also KVA rating Indicate the Maximum
Current Rating of a transformer with a rated voltage.

what are the breakdown voltage rating of mini- curcuit'transfarmer!
