A 2000 KVA, 4800-600V, 60 Hz, core type transformer operating at no load in the step down mode draws a magnetizing current equal to 2 percent rated current. The core has a mean length of 3.15 m, and is operating at a flux density of 1.55 T. The magnetic field intensity is 360A-t/m. Determine A) the magnitizing current; B) the number of turns in the two coils; C) the core flux; D) the cross-sectional area of the core.
