SEL- 2664S Data Sheet
100% Stator Ground Fault Protection
100% of the Time
Major Features and Benefits
The SEL-2664S Stator Ground Protection Relay provides an exceptional combination of protection, metering, monitor-
ing, control, and communications in a compact industrial package.
➤
Standard Protection and Control Features.
Protect your generator against stator insulation degradation and
ground faults, and monitor the neutral grounding resistor. When used with an SEL-2664 Field Ground Module,
the SEL-2664S Relay protects against rotor field insulation faults to ground. The stator ground protection works
for 100 percent of the stator winding and for all operating conditions, including when the generator is starting,
ramping, or offline using a novel multifrequency injection method in conjunction with the neutral overvoltage
elements.
➤
Operator Controls.
Take advantage of multiple methods for accessing and using the operator interface of the
relay. The front and side panels have eight LEDs that indicate the

Metering and Monitoring.
Use built-in metering functions to eliminate separately mounted metering devices.
Analyze SER reports and oscillographic event reports for rapid commissioning, testing, and post-fault
diagnostics. Additional monitoring functions include the Profile Report.
➤
Control Inputs and Outputs.
Take advantage of two internally wetted control inputs and four contact outputs
(one Form C and three Form A) for control and status indication.
