(a) If a motor at the end of a transmission line has a reactance of 8 ohms per phase, what is the maximum power which the machine can develop, given that the sender voltage is 4kV and the induced voltage Eo is also 4kV ( line to line ) ?

(b) How does this maximum power compare with the nominal rating of the machine?

(c) Calculate by how much the rotor poles move from their no-load position before the motor loses synchronism. Why is the angle less than 90 degrees

(d) Between which two voltages is the angle equal to 90 degrees when peak power has been attained ?
