Plot the phasor diagram of a synchronous generator with: Vph=800 V, I=0.8 A, la Ra = 20 V, la Xs = 120 V. Under these conditions this machine is operating with large system and it is supplying an RC-load with 0.8 power factor. b- What should be done to this SG inorder to double its delevered power and change the PF of its load to be lagging? Explain the construction and operation of the shaded-pole induction motor.
