Answer Posted / raul
the designs and ratings of electric machines such as
alternators, transformers etc are always decided by the
amount of losses taking place in d machines i.e. core loss
and copper loss. since the core loss depends upon the
applied voltage and copper loss depends upon d load
current, therefore the product of these dependent variables
i.e. voltage and current i.e. KVA is the acutal ratings.
