UPPCL TG-2, 19.03.2021 Shift II
Ans : (b) Series generator has very low voltage
regulation.
■ Series generator is negative voltage regulation
■ Shunt, separately and under compound generator is
positive voltage regulation.
Order of voltage regulation in descending order :-
Series > Differential > Over compound > Shunt >
separately > Under compound > Flat compound
Voltage regulation :-
This is percentage rise in terminal voltage form No-load
to full load expressed as rated full load voltage.
