The exciting current for a certain 50 kVA, 480-240V, 60 Hz transformer is 2.5 percent of rated current at a phase angle of 79.8 degrees. Sketch the equivelent circuit and phasor diagram for the no-load conditions and assuming operation is in the step down mode, determine:
A) the exciting current
B) the core-loss component of the exciting current
C) the magnitizing current
D) the core loss
