21) Assume that a damaged AC generator has new armature coils installed,the terminals are connected to the switchboard, and the machine is apparently ready to be paralleled with the bus. State in detail the procedure that you would follow to determine whether or not the phase sequence is correct.
23) What will happen if a generator with the wrong phase sequence is paralleled with the bus?
25) What will happen if a generator in parallel with others loses its field excitation?
