Product descriptions from the supplier
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.

10 Prohibitions for Transformer Installation and Operation!10 Prohibitions for Transformer Installation and Operation! Never install the transformer too far away—avoid placing it in remote mountains or wilderness. Excessive distance not only wastes cables and increases line losses, but also makes management and maintenance difficult. Never choose transformer capacity arbitrarily. Selecting the right capacity is essential. If the capacity is too small, the transformer may be overloaded and easily damaged—overloading beyond 30% should not exceed two hoursJames10/20/2025 -
