instead of kw

Answer / a.kossay

because transformers supply both real (active) and reactive
power so we have to specify it through a component summing
this two kind of power wich is the total power kva and also
because the power factor may vary through operation we cant
specify an active power for every power factor

Answer / dinkar dubey

transformers ratings are in kva as power has to transformed
from primary to secondary and power in electrical system is
product of volt*ampere .so tronsformers have va or kva or
mva ratings
