AVR-means automatic voltage regulator
AVR regulates the voltage of a generator. when voltage
drops, due to load increase, AVR gives voltage to exciter
and exciter more xecites the alternator and voltage improve.

AVR is a automatic voltage regulator who maintained the
terminal voltage of altornator

Answer / v.chandra shaker

AVR is an automatic voltage regulator,which not only
maintains the terminal voltage of an alternator but also to
maintain good voltage profile & power factor for which it
is connected. The AVR is linked with the main stator
windings and the
exciter field windings to provide closed loop control of the
output voltage with loaIn addition to being powered from
the main stator, the AVR
also derives a sample voltage from the output windings for
voltage control purposes. In response to this sample
voltage, the AVR controls the power fed to the exciter
field,
and hence the main field, to maintain the machine output
voltage within the specified limits, compensating for load,
speed, temperature and power factor of the generator.d
regulation of +/- 1.0%.

Answer / ramakishore karri

The automatic voltage regulator designed for to maintain the
constant voltage level.Depends upon the design it can be
used either in DC or AC voltages.what ever the load drawn
from the source the AVR keeps the voltage maintain the
predefined value

Answer / rama kishore karri

AVR is an automatic voltage regulator. The function of AVR is to keep the terminal voltage constant as load variation on power lines. Moreover, the output voltage variation is more likely to be severe because changes in the load power factor. For example an alternator AVR changes the alternator field current to compensate for either increase or decrease load voltage. A controller is used to increase or decrease the field current through field circuit. As the AC voltage falls field controller circuit causes to increase the flux and thus induces increased voltage and vice verse

Answer / mody

basically voltage regulator.

Answer / vikas gupta

Avr-automatic voltage regulator, it uses in ac alternators to regualte the voltage...its input is in ac and output is dc, it maintain the voltage as load variation on alternator, if load increases it gives the more dc voltage to exciter stator, so that more voltage could generate.
