if AVR fails in D.G set, what will be the effect?

Answer Posted / abdul ghani fatima fertilizer

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.
