Automatic voltage regulator.

Answer / raj

hai absolutely AVR stands for Automatic voltage regulator.
What it done means it compare the outcoming voltage of
generator with the Reference voltage assigned based on the
requirement. If it sense any variation in the level it vary
the field excitation.

Answer / m_anwar

AVR stands for Automatic Voltage Regulator.
So it is a regulating system which measure the generator
output then comparise with a reference value and generate a
positive or negative output to the excitation system to
decrease or increase the excitation to increase or decrease
the generator output voltage.

Answer / selvakumar t

AVR to maintain the rated out put voltage for DG set.

Answer / manoj kumar sahoo

AVR stands Automatic Voltage Regulator.
It gives constant regulated voltages to the Alternator for
DC excitation.Which is help of output voltages of generator.

Answer / deepak jha

AVR stand for Automatic Voltage Regulator work to control the output voltage of Generator in normal and Abnormal condition to maintain the system voltage as reference voltage. Its compare the output of Alternator and Controlling it as result in Changing of Excitation voltage of Field system.

Answer / ram kumar giri

AVR stands for automatic voltage regulator. The main function of AVR is to maintain the established voltage to the MSB or to the consumer. IT maintain the terminal voltage (which is preset) of the alternator. It is done by taking the sample from two phase to the AVR(which contains OPAMPS and other summing ckts) where it is compare with the preset value. Any deviation from the set value give an output (error in either direction (+ or -). This error is processed and finally a dc voltage output comes out from AVR which is fed to the excitation system. The sign will decide that excitation to be reduce or increase to maintain the set output voltage. This process is a continuous measure so the terminal voltage is always as set at AVR as per requirement.
