Generator relay 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.

Eaton’s Generator Relays (EGR5000) 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.

Common software tools

All E-series relays, including our E-series motor relays, use the same software

interface for easy access to information and programming of settings. Whether

you are using the front panel or the external software, the interface is the same

on all models.
