AS the name itself indicates it is a device which maintains
the required output terminal voltage & hence called as
Automatic voltage regulator,
a) In case of alternators the Terminal Voltage(TV) is ref.
& whenever the TV tend to fall due to load the drop is
immediately sensed & excitation is increased thereby the
required voltage is maintained in the output terminals.
b) In case of transformer the PT output is the ref. As the
voltage drops due to load an immediate signal is given to
Tap changer motor (raise/lower)which varies the tap
position in the transformer thereby achieving the required
Terminal voltage.
In Both these equipments AVRs are used,which is an
electronic device which has an inbuilt comparator &
regulator.
