Answer Posted / lakshmanan m
According to my opinion, manufacturer cant design the
particular transformer for specific load (capacitive or
inductive load) Thats why they dont give the power in KW.
Because KW= vxIx power factor. but power factor is
depending upon the load. So commonly they are give the KVA
power only. It means KVA= Vx I only. According to the load
we can calculate the KW rating.
