1. The core losses of the transformer is depend upon
the voltage while the copper losses depends upon the
current.

2. The load which is connected on the transformer is in the
terms of Kw. That's why the rating of the transformer is in
KVA.

why motor range is available 22kv,30kv,37kv,45kv and so on? why motor range is not available 21kv,24,25,26,27kv and so on?
