Answer / kailash

Either we have to reduce load or we have to increase speed
of prime mover by increasing fuel (diesel/steam) through
governor.

Answer / poorna

if the generator frequency falls during running condition
it may result in circulating currents if it running in
parallel with other generators or it is connected to grid,
remedy is to increase the speed of prime mover by any means
if not possible reduce the load

Answer / siva rao

the emf induced in alternator will reduced to very low value
and the generator will not serve any load.if the frequency
will fall to a lower value the excitation of the generator
must be increased.

Answer / mahi&junu

there are two methods. Either we can decrease the load connected or we can increase the excitation
