Generator relays

Eaton’s Generator Relays (EGR) are preferred by users because of their unmatched versatility and dependability. These multifunctional relays provide control and backup protection for medium- to large-sized generators. The EGR’s zone-selective interlocking function improves coordination and tripping time. The unique design provides complete metering, protection, and control in a single compact case, saving panel space and overall cost.

Eaton E-Series Relays

    Core features

    • Microprocessor-based protection with monitoring and control for medium to large sized generators. 
    • Complete metering of voltage, currents, power, energy, minimum/maximum and demand functions. 
    • Complete metering, protection, and control in a single compact case to reduce panel space, wiring and costs. 
    • Integral test function reduces maintenance time and expense. 
    • Zone selective interlocking improves coordination and tripping time, and saves money compared to a traditional bus differential scheme. 
    • Programmable logic control functions for providing customized protection and control solutions. 
    • Reduce trouble shooting time and maintenance costs- Trip and event recording in non-volatile memory provides detailed information for analysis and system restoration. 6000 cycles of waveform capture aids in post fault analysis (viewable using Powerport-E software) 
    • Minimum replacement time- Removable terminal blocks ideal in industrial environments 
    • Front RS-232 port and Powerport-E software provides local computer access and user-friendly windows based interface for relay settings, configuration, and data retrieval. 
    • Breaker open/close from relay faceplate or remotely via communications. 
    • Fast and easy troubleshooting, improved maintenance procedures and increased device security. Provides detailed traceability for system configuration changes. 
    • Relays self-diagnostics and reporting improves uptime and troubleshooting.

    Keep your operations up and running

    Eaton’s E-Series microprocessor-based protective relays offer reliable, secure and complete protection and control of power generation and distribution systems. Generator protection relays can be used to protect any size generator, and also be used as a primary or backup protection in standby generators and co-generation applications.
