SEL SEL-2664S Stator Ground Protection Relay

SEL-2664S

Stator Ground Protection Relay

Protect high-impedance grounded generators from ground faults at standstill, during startup,

and while running by using the multisine frequency injection and neutral overvoltage-based protection in the SEL-2664S Stator Ground Protection Relay.

Secure and Reliable—Apply the signal injection and neutral overvoltage in the SEL-2664S to protect high-impedance grounded generators from ground faults at standstill, during startup, or while running.

Eliminate Protection Blind Spots—Designate up to four individual injected frequencies to ensure that the protection does not have a blind spot during generator startup by using the unique multisine frequency injection in the SEL-2664S.

Redundant Protection—Implement redundant stator ground fault detection to improve system availability using two SEL-2664S relays in parallel.

Simplify Field Calibration—Use the SEL-4664 Calibration Module to automatically calibrate the SEL-2664S to account for installation-specific parameters and streamline the commissioning process.
