Product Detail

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.

Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
For users, when purchasing a 35kV new energy transformer, choosing between dry-type, mineral oil-filled, or vegetable oil-filled types involves multiple considerations. These include user habits, maintenance-free performance, safety and fire resistance, volume and weight, among others. However, cost differences are undoubtedly one of the most crucial factors.To illustrate the issue intuitively, this paper selects a three-level energy efficiency dual-winding new energy transformer with a rated ca

What is the connection group of a transformer?
What is the connection group of a transformer?
Transformer Connection GroupThe connection group of a transformer refers to the phase difference between the primary and secondary voltages or currents. It is determined by the winding directions of the primary and secondary coils, the labeling of their start and end terminals, and the connection mode. Expressed in a clock-like format, there are 12 groups in total, numbered from 0 to 11.The DC method is commonly used to measure the transformer's connection group, mainly to verify whether the con

Working Voltage in Power System
Working VoltageThe term "working voltage" refers to the maximum voltage that a device can withstand without sustaining damage or burning out, while ensuring the reliability, safety, and proper operation of both the device and associated circuits.For long-distance power transmission, the use of high voltage is advantageous. In AC systems, maintaining a load power factor as close to unity as possible is also economically necessary. Practically, heavy currents are more challenging to handle than hi

What is Steady State Stability in Power System?
Definition of Steady State StabilitySteady state stability is defined as the capability of an electric power system to sustain its initial operating condition following a small disturbance, or to converge to a state closely approximating the initial condition when the disturbance persists. This concept holds critical significance in power system planning and design, the development of specialized automatic control devices, the commissioning of new system components, and the adjustment of operati

What is the sequence for powering down the transformer?
What is the sequence for powering down the transformer?
The sequence for shutting down a main transformer is as follows: when de-energizing, the load side should be shut down first, followed by the power supply side. For energizing operations, the reverse order applies: the power supply side is energized first, then the load side. This is because: Energizing from the power supply side to the load side makes it easier to identify the fault range and take prompt judgment and handling measures in case of a fault, preventing the fault from spreading or e

What are the methods for switching operations of station transformers?
Let's take an auxiliary power system with two station transformers as an example. When one station transformer needs to be out of service, there are two operation methods: non-interruptive power supply and instantaneous power interruption. Generally, the method of instantaneous power interruption on the low-voltage side is preferred.The operation method for instantaneous power interruption on the low-voltage side is as follows:Open the 380V power incoming circuit breaker of the corresponding sec
