Extracted text: The armature resistance and armature reactance of a 3.5MVA, 11.5kV, Y-connected, 8 pole Synchronous Motor respectively are 60/phase and 200/phase. Determine the excitation voltage, power input, power output, total losses and efficiency at half of the rated load of machine and at a power factor of 0.7 leading. The total mechanical losses in the machine are 1.5kW and draw the phasor diagram. Write any assumptions made in doing above calculations.
