Q. 39 A 50 Hz synchronous generator is initially connected to a long lossless transmission
line which is open circuited at the receiving end. With the field voltage held
constant, the generator is disconnected from the transmission line. Which of the
following may be said about the steady state terminal voltage and field current
of the generator ?
(A) The magnitude of terminal voltage decreases, and the field current does not
change.
(B) The magnitude of terminal voltage increases, and the field current does not
change.
(C) The magnitude of terminal voltage increases, and the field current increases
(D) The magnitude of terminal voltage does not change and the field current
decreases.
Answer:(D)
