Product Description
The SVR-3 is a high-performance, oil-immersed three-phase automatic voltage regulator, designed to stabilize medium-voltage distribution lines. It operates as a self-regulating autotransformer, equipped with an advanced SVR smart controller that continuously samples voltage and current signals from the grid.
By automatically adjusting output voltage through an on-load tap changer (OLTC), the SVR-3 enhances grid efficiency, ensures power quality, and accommodates varying load demands. This system integrates current transformers (CTs), voltage transformers (VTs), and limit switches to manage regulation steps precisely and reliably.
Main Features
Wide Regulation Range
Up to ±20% voltage regulation via 16 tap steps, each at 2.5%, with self-developed high-capacity OLTC.
Advanced Smart Control
Built-in SVR controller with real-time monitoring, configuration, and remote communication via GPRS / GSM / Bluetooth.
Comprehensive Protection Functions
Includes automatic lock-out features for line faults, overload, overcurrent, and undervoltage, ensuring safe operation.
Flexible Control Settings
Supports adjustable voltage setpoints, step range limits, time delays, and user-configurable system parameters.
Additional Information
Payment Terms: 30% T/T in advance, 70% balance against copy of B/L.
Packaging: Export-grade plywood cases for maximum protection during transport.
Core Material Options: Copper or Aluminum windings available per customer requirement. Copper offers longer lifespan and better conductivity.
OEM Services: Custom logo/branding available for bulk orders.
