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.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
