Product Overview

The RVR-1 is a single-phase, oil-immersed autotransformer-based feeder voltage regulator, designed to maintain stable voltage levels across medium voltage distribution lines. It integrates an advanced RVR controller, which continuously samples voltage and current signals via voltage and current transformers, enabling precise on-load tap changing to adapt to grid load variations. The system improves overall grid efficiency by adjusting line voltage up or down according to real-time demand.

This regulator features a motor-driven on-load tap changer (OLTC) with step control based on real-time voltage/current feedback, ensuring fast and reliable response to network fluctuations. It is ideally suited for both 50Hz and 60Hz distribution networks, with voltage ratings ranging from 2.4kV to 34.5kV.

Main Features

• Wide Voltage Regulation Range:Provides ±10% voltage regulation (boost and buck) in 32 fine steps, each approximately 0.625%, for precise voltage control.
• Smart RVR Controller:Built-in advanced RVR-type controller developed in-house, supporting communication via GPRS/GSM and Bluetooth for remote monitoring and diagnostics.
• Automatic Protection Functions:Integrated lock-out functions for line fault, overload, overcurrent, and undervoltage conditions, ensuring equipment and system safety.
• Flexible Voltage Adjustment Settings:Supports adjustable voltage setpoint, step limits, timing delay between tap operations, and customizable operating parameters.
