Answer / blake australian engineer

An automatic voltage regulator, or AVR is used in a
generator to control the output voltage.
The AVR varies the excitation voltage (on the rotor) to
produce the desired voltage on the output terminals.

It is required because the excitation voltage changes as
the load (and power factor) change.

Hi...
i have one query.
in my native place We have Fridge , i put Stabilizer for fridge, spec is as follows
Input 130-270 ,Output- 230.....But the problem is that voltage we are getting from Electricity supply company is low it is below 110 V . so fridge doesn't start,,i think it is not meeting the spec of the stabilizer..is there any solution over it

Answer / sunil guru

AUTOMATIC VOLTAGE REGULATOR OR COMMONLY KNOWN AS STABILIZER IS TO GIVE REGULATED OUTPUT VOLTAGE.....

IT HAS MANY APPLICATIONS AND IT PREVENTS FROM UNDER AND OVER VOLTAGE FLUCTUATION...
AND SAGS ,SPIKES ,TRANSIENTS ,RUGGEDNESS IN VOLTAGES IS ALSO PREVENTED BY AVR

Answer / aayush

As the name itself suggests, it is used for regulating the
voltage. We normally use it with our costly equipments,
like TV or refrigerator, to save them from dangerous
voltage fluctuations.
