AVR

The VR-32 is a step-voltage regulating autotransformer equipped with Eaton’s Quik-Drive™ Tap-Changer, capable of ±10% regulation in 32 precise 5/8% steps. It supports single-phase or multi-phase configurations and is suitable for pole-, pad-, platform-mounted, or substation installations. Designed for both overhead and underground distribution networks, the VR-32 is ideal for utilities, substations, and sensitive industrial loads.

Key Features:

• Voltage Regulation: Operates with a ±10% boost/buck capability in 32 steps for continuous voltage control.

• Tap-Changer Technology: Integrated with Quik-Drive™ tap-changer ensuring rapid and reliable operation with a mechanical life exceeding one million operations.

• Construction & Durability: Sealed tank construction with 55/65 °C dual-rated insulation system. Units come with stainless steel hardware and protective coatings meeting ANSI and IEEE standards.

• ADD-AMP™ Capability: Allows increased current capacity when regulation range is reduced — up to 875 A depending on configuration.

• Control System: Compatible with Eaton’s CL-7 controller, supporting SCADA integration, reverse power detection, and customizable regulation logic.

• Surge Protection: Equipped with heavy-duty MOV-type series and optional shunt arresters for superior transient protection.

• Monitoring & Safety: Includes external position indicator, pressure-relief device, insulating fluid level gauge, temperature and pressure monitoring options, and built-in CT shorting protection.

Applications:

• Smart grids and distribution automation

• Industrial zones and large manufacturing facilities

• Renewable energy integration points

• Critical infrastructure such as hospitals, data centers, and communication networks

Available Options:

• FR3 natural ester fluid for environmentally friendly insulation

• Substation base or pole-mount bracket

• Remote control mounting and armored control cables up to 120 ft

• Stainless steel tank and nameplates

• Wildlife guards and NEMA 4-hole bushing connectors

All VR-32 regulators are factory-calibrated and tested in compliance with IEEE, ANSI, and IEC standards, and come with full documentation for installation, operation, and long-term maintenance. Eaton’s design prioritizes serviceability with features like hand-hole access, modular internal wiring, and external mounting for safe inspection and repairs.
