If Two Generators are working parellel in a network and
suddenly the field of one Generator get weakened What will
happened if there is no reverse power relay fixed in that
Generator panel????

Answer Posted / k.prakashchandra

Less excitation?. Then the generator will continue share the
load at leading power factor resulting in higher armature
current as the prime mover is still running and the terminal
voltage of the Gen is reduced.If this current exceeds the
set value ,Gen will trip on OCR which does not allow for
very low pf.
