Q#1 Transformers GATE EE 2014 MCQ +2 marks -0.66 marks

The core loss of a single phase, 230/115 V, 50Hz power transformer is measured from 230V side by feeding the primary (230V side) from a variable voltage frequency source while keeping the secondary open circuited. The core loss is measured to be 1050 W for 230V, 50Hz input. The core loss is again measured to be 500W for 138V, 30Hz input. The hysteresis and eddy current losses of the transformer for 230V, 50Hz input are respectively,

508W and 542W

468W and 582W

498W and 552W

488W and 562W
