Efficiency of the Transformer

what is the efficiency of the load transformer when it is at no load??


what is when it is connected at full load ?

I believe the efficiency of a load transformer is maximum at full load conditions.

the no load efficiency and p.f of t/f will be low under no load conditions
efficiency -10-25% under no load
95-97% under over load and full load conditions due to losses in the machine
p.f-lagging due winding losses that is beacuse of more winding inductance and low resistance
