Product: GF D563 A101, Digital Generator Protection Relay
Order Code: 3BHE046836R0101
Manufacturer: ABB
Primary Application: A numerical generator protection relay designed for comprehensive protection, control, and monitoring of medium to large generators (hydro, steam, gas, combined-cycle) in utility, industrial, and independent power plants. Part of ABB’s Relion® 650 series protection platform.
1. Core Overview & Positioning
The ABB GF D563 A101 is a member of ABB’s Relion® 650 series protection relay family, specifically configured for generator protection applications. The «GF» designation indicates its specialization in Generator and Feeder protection functions. It consolidates multiple protection, control, and monitoring functions into a single intelligent electronic device (IED), replacing numerous discrete relays and meters.
Key Philosophy: Provides complete generator management with advanced protection algorithms, extensive metering, and flexible communication options, ensuring maximum equipment protection, availability, and grid code compliance.
