subject: Auto Voltage Regulator Generator In Our Daily Lives [print this page] We may have heard of automatic voltage regulator and for some who are not aware of its functions, this article will tackle deep on its application and what it is in the electrical world.
Automatic voltage regulator is used mainly in industrial application to attain stability as well as regulation of various electrical devices. The AVR controls the field excitation in order to obtain the output of the alternator. It also maintains a constant voltage until a particular level that is different from the generator load and speed.
It is an electrical regulator that can automatically maintain the voltage level. It can utilize a passive, active electronic components or electrochemical mechanism. It can regulate one or more AC or DC voltages depending on its design.
AVR maintains the terminal voltage of an alternator, good voltage profile and the power for which it is connected. It is linked to the main stator windings and the exciter field windings to offer closed loop control of the output voltage.
Main Functions:
It is used as a rectifier and as a potential divider. A Rectifier is a device that is utilized for converting AC to DC. Since majority of the electric appliances can only work with a direct current and not on alternating current. As dividers, they are used for the input voltage splitting function to bring the desired output level.
It is also used as an amplifier. Amplifier works by comparing the voltage to the reference voltage. This is common in home and theater sound system that boost up the sound effects.
Generator Automatic Voltage Regulator is the one responsible for regulating the voltage in a generator. The AVR includes sensing loss protection and under-speed features. The excitation power is directly driven from the terminals of the generator.
Majority of home appliances require a stable electric power to make them running in good condition. And variation in the input current and voltage may cause some damage to these appliances. To avoid any mishappenings and damage to the devices and appliances, a voltage stabilizer is a must.
Now with advancement, the analog servo type automatic voltage regulators are replaced by digital AVR. They are more technically advanced with their performance and design. These devices are equipped with self functioning controls and startup functions that increase their portability and functionality. They are also designed with operating switches that makes it easy to operate.
Power engineers & Consultants is among the reliable Servo Voltage Stabilizer Supplier in India providing the widest range and models of Auto Voltage Regulator Generator. These devices are very useful for protecting your electrical devices, improvement of in power factory, as an electricity regulator and much more. With the many function of AVR, they are really inevitable part of our daily lives.
