Trafo losses depends on voltage and current only. voltage
influences the core loss or no load loss and current or
load influences the copper loss. no loss depends on power
factor of the load. thus efficiency is mainly governed by v
and I only. hence o/p whis is the ratio of (i/p - losses)/
i/p is controlled by v and I. Hence trafo rating is defined
in KVA no KW.
