Given three 1-phase 50kva 7.2kv: 2.4kv transformers

Using one transformer

A) Draw the correct circuit to serve a 2.4kv single-phase load from a 7.2kV source. If the load is 50kva at pf=.8 lagging, compute the secondary and primary phasor currents. is this a step-up or step-down application?

B)Draw the correct circuit to serve a 7.2kv single-phase load from a 2.4kv source. If the laod is 50kVa at pf=.8 lagging, compute the secondary and primary phasor currents. is this a step-up or step-down application?

C)Can a 9.6kV load be served from a 7.2kV source using this transfomer? if so, Draw the correct circuit, and determine the maximum load(kVA)

using three transformers...

D) can a 2.4 kV 3-phase load be served from a 12.47 kV 3-phase source? if so, state the HV and LV connection(wye,delta); draw the correct circuit and determine the maimum load (kVA).

E) On the circuit diagram of (D) inicate and evaluate all source currents (3), all Load current(3), and all transformers winding current (6), magnitudes only, no phase angles, at maximum load.
