Lehman Engineering Power Quiz
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.)
In which direction will the rotor of Generator #2 now rotate?
In which direction will the line current of Generator #2 now flow?
