In a transformer it is difficult to measure the efficiency by output-input measurement methods because

losses are abnormally high

output is out of phase with respect to input

the output is sinusoidal and hence cannot be measured

efficiency of transformer is usually high and hence extremely accurate measurements will be necessary
