Answer / saurabh kulkarni

automatic voltage regulator is the device which regulate
the voltage in two terms i.e transformer and in generators.
in transformer it is used for tap changing purpose. by tao
changing it increases or decreases the voltage.in
alternators it is used for excitation purpose.if there is
fall in the terminal voltage then excitation sensed and
increase the voltage.

Answer / m karthik

Automatic Voltage regulator is a device which is used to
regulate the excitation voltage and current, and also it
maintains the output voltage as constant.

Answer / raviteja

AVR means Automatic Voltage Rgulator.It is a device mainly eqipped with synchronous generator to maintain terminal voltage constant.The output of generator is taken and is stepped down to some value and is rectified that rectified signal is compared and error is generated and the compensation of voltage is made.Finally by excitation control it is going to keep the constant voltage level.I hope this will benefit for designing of AVR

Answer / dhivagar

it is a device which is connected to OLTCof the
transformer.it sense the i/p voltage fro the source &tap
changing action will takes place according ti that i/p

Answer / poonam chand

AVR is an Automatic Voltage Regulator .It
is important part in Synchronous Generators, it controls
the output voltage of the generator by controlling its
excitation current. Thus it can control the output Reactive
Power of the Generator

Answer / chetan h malaviya

AVR is nothing but voltage regulator at the generator
terminal when load is varying.

Answer / senthil

AVR ues of power transfomer to control the output voltgae
constant to irrespective load. to maintained output voltage
constant

Answer / ayid

its controlling device that maintain output terminal voltage
to the generator by excitation when the load connected.

Answer / gilbert

The automatic voltage regulator is automatically maintain a
constant voltage level.
The main working of AVR depends upon the laws of
electromechanical physics.It is consist of many passive and
active electrical components like adapters,capacitors,
diodes and thermostats.

Answer / basavaraj pujari

AVR is automatic voltage regulator which controls the terminal o/p voltage of the generator or alternator by controlling it's excitation current.morever avr responds this function within 1cycle and it control by 2modes manual mode and automatic mode.even avr used in transformer as a tap changer which fully control over the terminal voltage of transformer...
