Two identical 138 kV Y: 13.8 kV DELTA 100 MVA tap changing transformer each with a per unit series impedance of j.1 ohms are operating in parallel and supplying a 180 MVA load at 13.8 kV and .8 lagging pf. Transformer 1 has its primary tap in the 138 kV position and transformer 2 has its primary tap in the 134 kV position. Find the line currents in per unit and in amperes flowing on the load side from each transformer.
