GETCO Exam Paper (30-11-2008) In a transformer it is difficult to measure the efficiency by output-input measurement methods because efficiency of transformer is usually high and hence extremely accurate measurements will be necessary losses are abnormally high the output is sinusoidal and hence cannot be measured output is out of phase with respect to input efficiency of transformer is usually high and hence extremely accurate measurements will be necessary losses are abnormally high the output is sinusoidal and hence cannot be measured output is out of phase with respect to input ANSWER DOWNLOAD EXAMIANS APP
