1. If the avr is not giving any output voltage ie DC to the
excitor then no voltage build up will be there.
2. If the avr is not changing the dc voltage as per load
demand then voltage variation will be observed.Which means
the automatic rerulation function of avr wrt load is not
working.Hence avr needs replacement.
