SEL-2664S Stator Ground Protection Relay

SEL-2664S

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.

 

Applications

100 Percent Stator Winding Protection, 100 Percent of the Time - Apply the frequency 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 using SEL’s unique frequency injection. The SEL-2664S is the only product that allows redundant injection-based stator ground fault detection.
