A three phase transformer delivers a load of 83 MVA at 0.8 p.f. lagging and 138 KV (line-to-line). The primary voltage under these conditions is 14.34 KV (line-to-line), the apparent power is 86 MVA and the power factor is 0.78 lagging.

A. Find the transformer ratio.

B. Find the series impedance representation of the transformer.

C. Find the primary apparent power and power factor as well as the voltage when the load is 75 MVA at 0.7 p.f. lagging at a voltage of 138 KV.
