EXAMPLE 3.19 A NY connected 3-phase transaer 22 kV (A)/345 kVM (line-to-line). The transform is feeding 500 MW and 100 MVAR to the grid (345 kV). Determine the MVA and voltage rating of each unit (single-phase). Compute all currents and voltages of both magnitude and phase angle in all the windings (primaries and secondaries). Assume each single-phase transformer to be ideal. as shown in Fig. 3.57 has a voltage ratio of
