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.

Strange Devices on Transmission Lines: 5 Little-Known Practical Functions（1）1 Aviation Warning SpheresAviation warning spheres, also known as reflective safety spheres, are used on overhead transmission lines near airports, especially on extra-high-voltage (above 220kV) lines and river-crossing transmission lines. Highly visible aviation marker spheres (aviation warning spheres) must be installed along the lines to provide warning signals.The aviation marker sphere (aviation warning sphere) has a diameter of ф=600mm. The sphere can be manufactured in various bright coloLeon09/04/2025 -
Transmission LineIn transmission lines, a "π" connection involves breaking the original line from Substation A to Substation B and inserting Substation C, forming a "π" configuration. After the "π" connection, the original single line is divided into two independent transmission lines. Following the "π" connection, Substations B and C may both be powered by Substation A (in this case, Substation C receives power via a feeder from Substation B's busbar, or possibly from another voltage point within Substation B);Encyclopedia09/04/2025 -
What are the principles of forced re-energization of transmission lines?Principles of Forced Re-energization of Transmission LinesRegulations for Forced Re-energization of Transmission Lines Correctly select the forced re-energization end of the line. If necessary, change the connection configuration before forced re-energization, taking into account the reduction of short-circuit capacity and its impact on grid stability. There must be a transformer with its neutral point directly grounded on the busbar at the forced re-energization end. Pay attention to the impactEdwiin09/04/2025 -
Analysis of Accident Handling in Transmission LinesAnalysis of Transmission Line Fault HandlingAs a fundamental component of the power grid, transmission lines are widely distributed and numerous, often exposed to diverse geographical and climatic conditions, making them highly susceptible to faults. Common causes include overvoltage, pollution flashover, insulation damage, tree encroachment, and external damage. Line tripping is one of the most frequent faults in power plant and substation operations, with fault types including single-phase-to-Leon09/04/2025 -
The difference between transmission and distribution linesTransmission lines and distribution lines are both used to carry electrical power from one location to another. However, they differ significantly in key aspects such as primary function, voltage levels, phase configuration, and conductor placement. These differences are essential for understanding their distinct roles in the power system.The Difference Between Transmission and Distribution Line is given below in the tabulated form.Electricity generation is a critical component of the power systEdwiin09/04/2025 -
