Dear Friends.
If Generator is running in Island mode then it will be
tripped due to excitation failure so all the load will be
cut off, and if the Generator is running in Parallel even
then it will be tripped on under excitation.
But if the excitation protection fails then it will be
tripped on reverse power.
And if there is no any protection then during parrallel
running the faulty generator shall act as motor, and if
Generator running in Island mode it will be continuous run
without output rated voltage so loads shall not be
continued.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
