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 equivalent 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 magnetizing current; (d)the core loss.
