Transformer is the statics device.actually rating of the
machine (kva or kw) depends upon the power factor since the
load power factor to which transformer is supplying power
is not known , it may be capacitive ,inductive , or
resistive that is why its rating is in kva and not in kw.
P=VIcosø
cosø is the depen upon the load & load not cosider the
manufacturing compony of transformer.then only VI
consider.so its rating is in kva.

Atwhat condition reverse power relay will act?
