    I believe the efficiency of a load transformer is maximum at full load conditions.
    Are you sure? This action cannot be undone.

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


    what is when it is connected at full load ?
    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
    Are you sure? This action cannot be undone.
