Lehman Engineering Power Quiz
"Synchronous Generators"

Consider the electrical one line diagram below.

Two identical synchronous generators are tied to the distribution line bus. Both are delivering power to the circuit and the direction of the line currents from both generators is as shown. The rotors of both generators are turning in the same clockwise direction as shown.

The prime mover of Generator #2 is now disconnected and removed. (The prime mover is the mechanical torque which forces the rotor to turn.)

Question #1:
In which direction will the rotor of Generator #2 now rotate?

Question #2:
In which direction will the line current of Generator #2 now flow?
