SEL-2664

Field Ground Module

Prevent catastrophic generator failure with the SEL-300G Generator Relay and SEL-2664 Field Ground Module.

Plug-In Compatibility With SEL-300G
Designed to work with the SEL-300G Generator Relay to provide complete generator protection. Add the SEL-2664 to the SEL-300G to protect all critical components in your generator.
Measure Field Resistance Before and After Start-Up
Measure field-to-ground resistance before you start the generator rotating. Protect your generator from excessive starting stress by detecting field ground faults prior to start-up. Continuously monitor resistance during operation.
Isolate Field Noise and Ground Potential
Avoid potentially hazardous voltages from a high-voltage dc field to the relay or relay panel using digital fiber-optic communication of resistance values from the SEL-2664. Eliminate tedious calibrations and variations common when using analog signals to the relay.
No Settings in the Field Ground Module
The SEL-2664 is ready to connect to your generator field right out of the box. Simply turn on the 64F element, and set the port, alarm, and trip values in the SEL-300G. ACSELERATOR® QuickSet SEL-5030 Software makes it easy.

Use the SEL-2664 Field Ground Module with the SEL-300G Generator Relay to provide a complete generator protection package.

The SEL-300G provides comprehensive
generator protection:

• One-hundred percent stator ground fault protection

• Current differential protection

• Out-of-step protection

• Overexcitation detection

• Directional power elements

• RTD-based protection with the SEL-2600A or SEL-2600D RTD Module

• Metering and reporting

The SEL-2664 provides additional protection and monitoring:

• Accurate protection, even when the generator is not running

• Ground monitoring on field circuits from 48 to 825 Vdc continuous

• Complete isolation using the SEL-2812 Fiber-Optic Transceiver to the SEL-300G

• Easy setup with zero settings in the SEL-2664

• Best-in-class accuracy at 500 ohms and ±5 percent

• Best-in-class operating temperature from -40° to +85°C
