When input to generator increased when it is synchronised, speed of alternator get disturbed which inturn leads to the change in frequency,when frequency gets change synchronization is no long.
By reducing the output fusing of a generator, the total output of the generator will also be reduced. The capacity of the generator will remain the same but the fault trip point will be lowered.
A coil of wire spins in a magnetic field
The rated voltage of a generator decreases due to many causes such as armature reaction, overloading of the generator and AVR failure/ weak excitation voltage.
If load on a generator is greater than the generator can provide, the generator will begin to slow down. If it slows down too much, it will lose synchronism.

presure i increased when more particels hit the side
The unused power goes to "waste"
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
NPV decreases when the cost of capital is increased.
The area is increased by 300%.
what happens if petrolium price is hike
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator
