Automatic Voltage Regulator (AVR)
AVR
Automatic Voltage Regulator (AVR) with on Load Tap changer
The On Load Tap Changer, automatic voltage regulator (AVR) is used to compensate the voltage drop in the electrical networkâ?? so that customers at the line end receive the same average voltage value as those closer to the source.
The voltage value reduction affects the operational quality of the rotating machines and increases the losses due to the high current drawn due to the voltage reduction. It also affects the quality of the illuminating system.
EGYTRAFO Group produces the Automatic Voltage Regulator (AVR) with rating up to 630 A & 9 tapping positions.
-The AVR is flange mounted (ON TANK) or (IN TANK) type according to the rating of the transformer and a remote tap changer control cubicle (RTCC)
Our ranges are up to 630 A, up to 22 KV and more than 5 taping positions on request.
Automatic Voltage Regulator (AVR) applications:
you can use it as a safely starting machines such as induction motors and synchronous motors
Also, boosters to give a small boost to distribution cable for compensating the voltage drop
you can get the same advantage of the Variac
Automatic Voltage Regulator (AVR) advantages:
Increased KVA rating for a given size and mass
Less amount of copper
Due to the smaller size, the cost is less compared to a two â?? winding transformer
The resistance and reactance are less compared to a two â?? winding transformer and hence it has superior voltage regulation
The Volt-ampere rating is more compared to a two â?? winding transformer
It is possible to get a smooth and continuous variation of voltage

Svc single and three phase, high precision, and automatic voltage regulator series is composed of contacting auto-transformer, servo motor and automatic control circuit. When power grid voltage isnâ??t stable or external load changes, the machine could sample the control circuit automatically and send a signal to drive servo motor to adjust the location of the auto-transformerâ carbon brush, ultimately adjusting the output voltage to the rated value and reach the stable state., AVCseries is equipped with line pass-through function .It has a number of advantages like various models, complete specification range, and sophisticated appearance. It can operate reliably and continuously for long period with no waveform distortion and high efficiency. The machine has short time delay and over-voltage protection. Whatâ more, additional features like extending delay and under-voltage protection can be added under requests. Svc can be widely applied to any place with electricity usage. As an ideal voltage-stabilized power supply, it makes sure that your electrical equipment operate smoothly.
