automatic voltage booster in the feeders or distribution systems

automatic voltage booster is primarily used by the electric utility to compensate for the voltage drop in the feeders or distribution systems. 

In addition, the term step voltage regulator is often used to refer to utility SVR.

two distinct types of auto load booster

Applied in the utility’s distribution systems are generally medium-voltage mechanical high voltage auto load booster (SVR). It should be noted that there are two distinct types of AC auto load booster: Medium-voltage step voltage regulator(mechanical) and the Low-voltage step voltage regulator(mechanical or electronic). The difference in their operation and design clearly demonstrate that their applications are not the same. The latter is intended to protect end-user devices from overvoltage and undervoltage conditions.

A wide range of single phase step voltage regulators

We are involved in manufacturing a wide range of single phase step voltage regulators.The high voltage auto load booster are used to get stable input voltage, irrespective of the voltage received from electricity authorities. Additionally, these stabilizers also prevent the transformer and other electrical equipment from getting overloaded. AVR take care of wide voltage variation ranges continuously and in on load conditions.

automatic voltage booster for a long life

The automatic voltage booster increase the life and improve the performance of electrical appliances. These stabilizers protect the electronics against fluctuating power supply. These stabilizers are automatic in their operation and produce a stabilized power supply then and there when it detects a fluctuation. In these automatic voltage stabilizers, there are automatic voltage stabilizers to show output. 

The classification of high voltage auto load booster

(1) contact type voltage regulator

Contact voltage regulator application earlier, this high voltage auto load booster contact vibration frequency is slow, there is mechanical inertia and electromagnetic inertia, low voltage regulation accuracy, contact prone to sparks, radio interference, poor reliability, short life Has been eliminated.

(2) transistor regulator

With the development of semiconductor technology, the use of transistor regulator. The invention has the advantages that the switching frequency of the transistor is high, and no spark is generated, the adjustment precision is high, and it has the advantages of light weight, small volume, long life, high reliability and small radio interference. It is widely used in Dongfeng, Middle and low models.

(3) integrated circuit regulator

Integrated circuit regulator in addition to the advantages of transistor regulator, but also has a small, installed in the generator inside (also known as built-in regulator), reducing the external wiring, and cooling effect has been improved, is widely used in Santana The Audi and other car models.

(4) computer control regulator

The computer control regulator is a new type of regulator used in the car. After measuring the total load of the system by the electric load detector, the signal is sent to the generator computer, and then the generator voltage regulator is controlled by the engine computer, Open magnetic field circuit, which can reliably ensure that the electrical system to work properly, so that the battery charge sufficient, but also reduce the engine load and improve fuel economy. Such as Shanghai Buick, Guangzhou Honda and other car generators use this regulator.

How an automatic voltage booster works

How an automatic voltage booster works: In the first place the automatic voltage booster monitors the output voltage and controls the input voltage for the exciter of the generator. By increasing or decreasing the generator control voltage, the output voltage of the generator increases or decreases accordingly. The automatic voltage booster calculates how much voltage has to be sent to the exciter numerous times a second, therefore stabilizing the output voltage to a predetermined setpoint. When two or more generators are powering the same system (parallel operation) the step voltage stabilizer receives information from more generators to match all output.
