Three single phase transformers are used to form a three-phase transformer bank rated 13.8kV (delta)/120kV (wye). One side of the transformer bank is connected to a 120kV transmission line, and the other side is connected to a three-phase load of 12MVA at 0.8 power factor lagging.

Determine the turns ratio of each transformer and the line current of the bank at the 120KV side.
