Features:
- Complete, Secure Protection for Small to Medium Sized Generators
- Advanced Protection and Monitoring with RTD Thermal and Vibration Inputs
- Global Acceptance in Renowned Protection Relay Product Family
The 489-P5-HI-A20-E operates as a comprehensive generator protection relay, providing complete, secure protection for small to medium sized generator assets across diverse industrial applications. It continuously monitors generator electrical parameters, thermal conditions, and mechanical health to prevent costly damage from faults, overloads, and abnormal operating conditions. Seamless integration with monitoring systems is standard with the 489-P5-HI-A20-E, however using its advanced communication capabilities will allow seamless data exchange with SCADA and energy management platforms for comprehensive system visibility. The 489-P5-HI-A20-E has incorporated significant improvements in protection functionality and user interface design over previous relay generations in addition to maintaining global acceptance as a member of the most renowned protection relay product family in the market.
The 489-P5-HI-A20-E provides essential protection functions critical to generator safety, and is a vital component of the generator protection scheme, directly affecting the proper, normal operation of the overall power generation system. One 489-P5-HI-A20-E relay is required per generator depending on the protection requirements and application complexity. The 489-P5-HI-A20-E features a large, user-friendly front panel interface with a display that is easily readable in direct sunlight, enabling convenient local monitoring and setpoint access.
For enhanced reliability applications, the 489-P5-HI-A20-E system supports comprehensive diagnostic capabilities including IRIG-B time synchronized event records, waveform capturing, and data loggers for detailed troubleshooting analysis. In addition to standard protection functions, the advanced configuration also performs automatic event logging. The 489-P5-HI-A20-E protection system executes monitoring using the internal RTD inputs specified for stator and bearing thermal protection. Using this method, the protection system continually monitors the health of generator thermal conditions. If the system detects that temperatures exceed configured thresholds (outside acceptable operating levels), it will automatically initiate protective actions and place an event in the event record.
The 489-P5-HI-A20-E GE Generator protection relay may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
