GETCO Exam Paper (30-11-2008) 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 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 ANSWER DOWNLOAD EXAMIANS APP
