Answer Posted / student
For the same KVA rating we can use the transformer with
corresponding increase or decrease in the voltage and load
current.Eventhough theoretically it is possible no
manufacturers prefer because of the practical difficulties
as explained in Ans # 2 and 3.
So combining Ans # 2,3 and 9 we can say its not practically
advisable to use the transformers in such a way.
