Transformer is mere equipment which transforms the voltage
and current as per the requirement. KW are rated for
equipments which converts electrical energy to other energy.
Transformer rating in KVA is due to it converts electrical
energy to electrical energy and all electrical ratings are
done only in voltage and current or combination of both,
like CB rating in Voltage and current, Bus bar rating in
amperes etc.
