SVR Series Automatic Line Voltage Regulator

Product Overview

The SVR series automatic line voltage regulator is essentially an autotransformer with continuously adjustable voltage. According to the condition of the line voltage, the gear of the on-load tap-changer can be automatically adjusted to change the transformer ratio, ensuring that the output voltage remains stable within a certain range. It is suitable for power supply lines with relatively long supply distance, large power supply load, large voltage fluctuation, and power quality that does not meet the standard. It can also be used for industrial and mining enterprises whose voltage quality cannot meet production needs.

Key Features

• Autotransformer structure realizes on-load automatic voltage regulation within 20%.
• Excellent control performance and communication function, enabling the “four remote” functions: telemetry, remote signaling, remote adjustment, and remote control.
• Anti-interference measures ensure normal operation of the controller.
• The controller provides high and low position limit protection to prevent the tap changer from jamming.
• The on-load tap-changer oil tank is isolated from the autotransformer body oil tank.
• Small size, large capacity, light weight, low loss, and easy installation.
• Energy-saving effect and high reliability.

Applications

• Power supply lines with relatively long supply distance.
• Lines with large power supply load and large voltage fluctuation.
• Power supply lines where power quality does not meet the standard.
• Industrial and mining enterprises whose voltage quality cannot meet production needs.
• Rural power grid long-distance transmission points; the regulator can extend the power supply radius of the substation.

Technical Specifications

Why Choose This Product?

The SVR series automatic line voltage regulator addresses voltage instability on long-distance, high-load lines by automatically adjusting the on-load tap-changer to keep output voltage within a set range. Its autotransformer design supports automatic regulation within 20%, while anti-interference measures and high/low limit protection help ensure reliable controller operation and prevent tap changer jamming. The regulator can extend the substation’s power supply radius, effectively reduce line loss and distribution loss, and does not require power-off when put into operation, making it a practical solution for rural power grids and industrial and mining enterprises with power quality issues.
