Answer Posted / shakir
there are so many reasons:
1.the exciter might have problem
2.the ac produced in exciter is converted into dc before
supplying it to the rotor.the diodes used for this purpose
might have problem.
3.when u start the generator there should be a residual
magnetism to induse the voltage.if u will not use the
generator for long time, it will loose that residual
magnetism.for that purpose u have to give flash over
voltage.
4. the exciter winding might be grounded.
5. the input (D.C.from voltage regulator)voltage to the
exciter is not enough to create flux in the exciter.
6.faulty stator winding
