The term AVR refers to an electronic product that can automatically maintain the terminal voltage for a generator at a preset value. The electronic device would try to do the said task if the generator operating temperature or load changes. That means it works to regulate variations in voltage for a reliable and constant power supply. With no AVR, voltage could spike, surge or sag, thus damaging electrical equipment. Automatic voltage regulator suppliers in UAE, too, have various products for you to pick from. Therefore, it is potentially difficult to make the choice that suits your business equipment loads. Knowing how the device works and what its features are can help you with the purchase.
In What Way Does This Device Work?
An AVR can sense the voltage coming from the terminals of a generator, and it can compare the same to a stable voltage reference, thereby controlling the equipment’s output voltage. Then, the so-called error signal, a voltage type, is utilized for adjusting the generator field current through an increase or reduction in the flow of current to a component called exciter stator. Then, the said generator component leads to a higher or lower electromotive force at the primary stator terminals. Now, we will discuss the features of the products available with automatic voltage regulator suppliers in UAE or elsewhere.
How To Pick An AVR
All automatic voltage regulators appear similar, but these vary slightly in color and size. Nevertheless, all of these products have comparable features. The following list of AVR features can help you to discover the product that suits your application. Therefore, be sure of keeping these in mind when doing business with any of the generator suppliers in Sharjah as well.
Voltage Regulation
There would be optimum voltage regulation if the voltage value is the same as every electrical equipment load. As a generator maintenance company in UAE, we know that many things can impact voltage regulation. Some of these factors are cable and wire type and size, transformer reactance, motor starter, power factor and circuit design. Irrespective of these possible obstacles, the regulation of voltage must be capable of being adjusted to a ±1% accuracy. This requirement would remove voltage unbalance issues in a three-phase generator system while minimizing voltage deviations.
Input Voltage Range (IVR)
Specifying your IVR is among the first few steps in choosing the right product from one of the automatic voltage regulator suppliers in UAE too. The IVR should be shifted and broad, since line voltages come down to a greater extent than these go up. This feature enables low voltage correction to a greater degree, as opposed to high correction. Besides, it allows making the electronic device more capable of being configured to any boost or buck function.
Voltage Accuracy
Improving voltage level accuracy is the main task of an AVR. So, you should consider the optimum level of accuracy for your specific application when doing business with any automatic voltage regulator suppliers in UAE as well. The accuracy factor depends on how much critical load you require. Usually, an AVR functions in a circuit, where it is impossible to achieve voltage regulation by altering the conductor size.
Conclusion
In applications with big concerns about voltage impulses, transients and spikes, it is vital to deem transient suppression a critical characteristic. More characteristics than the above-mentioned are vital for an AVR to work reliably, especially in a demanding application. So, remember all of these and more features when working with any generator spare parts suppliers in UAE too.
