Product Overview

The ABB REG216 numerical generator protection relay adopts a modular rack-based architecture, designed for protection and supervision of synchronous generators, block transformers and large motors in power plants. It integrates abundant configurable protection functions including stator differential, loss of excitation, over/under voltage, over/under frequency, negative sequence overcurrent, thermal overload and backup protection. It supports flexible software function selection and hardware module expansion, with high-precision signal sampling and built-in fault recording. Built for continuous long-term operation in power plant control rooms, this unit prevents generator damage and system outages caused by aging or faulty original protection devices. Manufactured to strict power industry standards and fully tested, it serves as a dependable replacement spare part for generator protection system maintenance and fault repair.

Core Application Advantages

• Low Failure Rate Operation: Constructed with industrial-grade materials and circuitry, delivering strong stability and durability to cut recurring maintenance expenses.
• Fast Fault Recovery: Modular rack structure enables quick module replacement. Engineers can finish system repairs rapidly to minimize power generation downtime losses.
• Wide System Compatibility: Fully compatible with original ABB REG216 generator protection system architecture. Supports multiple communication protocols for SCADA connection, no complex program adjustments needed after installation, bringing zero adaptation cost.

Typical Application Cases

• Industrial System Emergency Maintenance: Emergency replacement of defective generator protection relays in power plants to restore generator multi-function protection rapidly.
• Long-term Spare Part Reserve: Kept as regular inventory for thermal power, hydropower plants and industrial self-generation stations, easing procurement bottlenecks and long lead times of original imported spare parts.
• Automation System Upgrade: Matches legacy generator protection cabinets during power plant reconstruction and generation system intelligent transformation.
