Product descriptions from the supplier

Description

Overview

The RVR-1 Feeder Automatic Voltage Regulator is a single-phase, oil-immersed autotransformer equipped with an advanced RVR controller and an on-load tap changer (OLTC). Designed to optimize grid efficiency, it dynamically adjusts voltage levels by monitoring and sampling voltage/current signals, enabling precise load management through step-by-step voltage increments ("boost") or decrements ("buck").

Key Features

Voltage Regulation

  • ±10% voltage adjustment range (32 steps of 0.625% per step).

  • Rated for 2,400 V (60 kV BIL) to 34,500 V (200 kV BIL), compatible with 50 Hz and 60 Hz systems.

Smart Controller Technology

  • Built-in RVR controller with GPRS/GSM and Bluetooth connectivity for remote monitoring and control.

  • Self-developed algorithms for real-time voltage/current data acquisition and adaptive adjustments.

Integrated Protection Functions

  • Lockout mechanisms for fault conditions: line fault, overload, overcurrent, and under-voltage.

  • Adjustable settings: voltage reference, step range limits, transition delays, and system parameters.

Rugged Construction

  • On-load tap changer with motorized drive, current/voltage transformers, and limit switches.

  • High-creepage porcelain bushings and MOV-type surge arresters for enhanced insulation and surge protection.

Standard Features

Operational Components:

  • Tap position indicator with ADD-AMP adjustment.

  • Motorized tap changer with dedicated power supply.

  • Control cabinet with removable front panel and conformal-coated circuit boards.

Safety & Maintenance:

  • Oil drain valve with integrated sampling port.

  • Pressure relief device and oil sight gauge for condition monitoring.

  • Lifting lugs and corrosion-resistant nameplates for easy installation and identification.

Applications: Ideal for utility distribution networks, industrial facilities, and renewable energy systems requiring stable voltage regulation under dynamic load conditions.

Technical Parameters

Some of the voltage ratings include:50Hz: 6kV, 6.35kV, 11kV, 15kV, 22kV, 33kV60Hz: 7.62kV, 13.2kV 13.8kV, 14.4kV, 19.92kV, 34.5kVCustomization is available.
