Overview
Ang RVR-1 Feeder Automatic Voltage Regulator usa nga single-phase, oil-immersed autotransformer nga gisulod og advanced RVR controller ug on-load tap changer (OLTC). Gigihapon nga gibag-o ang mga nivel sa voltage pinaagi sa pag-monitor ug pag-sample sa mga senyal sa voltage/current, nagpadayon nga mobag-o sa precise load management pinaagi sa step-by-step voltage increments ("boost") o 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.
