Answer Posted / lalgpt
Transformer rating is always on KVA that is
Kilo Volt Ampere Simply Volt ampere
but equation of power is VICos()
And the transformer has two losses one is copper loss
and the other is the core loss these two losses
are depending on current (I) and Voltage(V) only not
on Cos() that is why rating is in VA
