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 3.15meters, and operated at a flux density of 1.55 T. The magnetic field intensity is 360 A-t/m. Determine (a)the magnetizing current (b)the number of turns in the two coils; (c)the core flux; (d)the cross sectional area of the core.
