GE SR489-P5-L0-A20-E｜Generator Management Relay｜
Core strengths
Comprehensive protection: covering all types of faults in the generator under all operating conditions, with stator grounding protection reaching 100% coverage, suitable for generators of different capacities.
Flexible Communication: Compatible with multiple protocols, supports local/remote monitoring, adapts to SCADA systems and intelligent power station networking.
Easy to maintain: drawer style design, module replacement without power outage, reducing downtime.
Accurate monitoring: 12 RTD+4 analog inputs, real-time monitoring of key parameters such as temperature and vibration, and early warning of faults.
Data recording: waveform and event recording function, assisting in fault analysis and system optimization.
Typical application scenarios
Power plant/self owned power plant: As the main protection device of the generator, it provides differential, overcurrent, overvoltage and other protections, and is connected to the DCS/SCADA system.
Substation: Ensure the safety of synchronous generator grid connection, monitor grid connection parameters, and achieve automatic synchronization and fault tripping control.
Industrial power generation system: Suitable for 25Hz special frequency generators, used for protecting self owned power generation equipment in industries such as mining and metallurgy.
