Could explain briefly of over excitation in transformer.
Answer Posted / k.prakashchandra
In brief . Flux = K V / f . If the voltage increases or frequency decreases flux will increase when the other factor remains the same . That's why you can not give excitation unless the gen picks up at least 90 % of the rated speed in case of generator
