Description

The RVR-1 is a single-phase, oil-immersed automatic voltage regulator based on an autotransformer design. It is equipped with an advanced RVR controller that continuously samples voltage and current signals from the distribution line. Through an integrated on-load tap changer (OLTC), the RVR-1 dynamically adjusts voltage levels to match load conditions, improving voltage stability and system efficiency.

The system combines a tap-changing transformer, motor-driven switching mechanism, and intelligent control to provide automatic voltage regulation with high precision and reliability.

Key Features

• Wide Regulation Range:Regulates voltage from -10% (buck) to +10% (boost) in 32 fine steps, approximately 0.625% per step.

• Smart Control System:Features a self-developed RVR controller with support for GPRS/GSM and Bluetooth communication, enabling real-time data acquisition and remote control.

• Advanced Protection Functions:Integrated lock-out protection against line faults, overloads, overcurrent, and undervoltage conditions.

• Customizable Settings:Supports adjustable voltage reference values, tap step limits, tap delay time, and user-defined control parameters.
