AVR nothing but stabilizer,control the output voltage of generator output voltage through dc field excitation current

Answer / er. tarun joshi

avr is an important component of an alternator or a
synhronous generator , normally with an alternator 2 more
generators are coupled on the same shaft , 1 is dc gen. or
dynamo & other is pmg or permanent magnet gen. , dynamo
provides supply to the rotor field windings of the main
alternator & the field windings of dynamo are excited by an
avr which maitains a constant current-frquency-voltage , in
the suply to dynamo field winding , through suitable solid
state devices , the avr gets it input supply from pmg &
then process it accordingly , thus overall an avr maintains
the output voltage of an alternator by regulating the field
excitation current , & thus regulating the reactive power.

Can somebody tell me what is the automatic voltage
regulator with servomotor?

Answer / dinbandhu kumar nayak

AVR increases or decreases exciter current for a more
linear voltage and frequency.

Answer / satish babu

AS teh name itself explains it regulates to the ref.
voltage,
a) In case of generator the Terminal Voltage is ref. & its
o/p is excitation voltage thereby regulating TV
b) In case of transformer the PT input is the ref. & Tap
changer is continuosly operated until the PT input is
regularised. In Both these cases AVR are used,

Answer / d.k.mathur

This is a Controller for automatic operation of OLTC(on
load tap changer) for a Power Transformer as per pre
settings of Higher & Lower Voltage Limits.
This Controller switches OF & ON the OLTC for keeping
output voltage of transformer as per set limit and works
contineously.

Answer / j.sandeep soni

Basically this is a automatic controller or mean to say
that a automatic controlling switch mainly used for control
the voltage of any source, load or any electrical network.
Its main uses are automatic operation of OLTC (on load tap
changer) for a Power Transformer, to regulate the
excitation voltage in generator, temp control of electrical
furnace etc.
