SEL-2664

Field Ground Module

Add the SEL-2664 Field Ground Module to the SEL-300G or SEL-700G to protect all the critical components in your generator with one comprehensive relay. Or, add the SEL-2664 to the SEL-2664S to complete ground fault protection on both the rotor and stator.

Plug-In Compatibility—Add the SEL-2664 Field Ground Module to the SEL-300G Generator Relay, SEL-700G Generator Protection Relay, and SEL-700GT Intertie Protection Relay to protect all critical components in your generator. Or, add the SEL-2664 to the SEL-2664S Stator Ground Protection Relay for complete rotor and stator ground fault protection.

Continuous Monitoring—Measure field-to-ground resistance before the generator starts rotating. Protect your generator from excessive starting stress by detecting field ground faults prior to startup. Continuously monitor resistance during operation.

Optical Communication—Avoid exposure to potentially hazardous dc field voltages by using digital fiber-optic communications. Eliminate tedious calibrations and variations that are common when sending analog signals to the relay.

Rugged Design—Built to the same high standards as SEL protective relays, the SEL-2664 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. The printed circuit boards are conformally coated to provide an additional barrier to airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture.

Plug-In Compatibility With SEL-300G, SEL-700G, or SEL-2664S
Designed to work with the SEL-300G or SEL-700G Generator Relays to provide complete generator protection. Add the SEL-2664 to the SEL-2664S to protect rotor and stator windings from ground faults.

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, SEL-700G, or the SEL-2664S. acSELerator QuickSet Software makes it easy.

Operate Reliably Under Extreme Conditions
Built to the same high standards as SEL protective relays, the SEL-2664 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. The printed circuit boards are conformal coated to provide an additional barrier to airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.
