Stator ground protection relay for IO, communication protocols
Schweitzer Engineering Labs' SEL-2664S Stator Ground Protection Relay provides stator winding protection with built-in I/O contacts and multiple communications protocols including Modbus, IEC 61850, and FTP.
Schweitzer Engineering Labs' (SEL) SEL-2664S Stator Ground Protection Relay provides standalone stator winding protection with built-in I/O contacts and multiple communications protocols. The SEL-2664S can be used as a standalone protection device or with third-party generator protection. The SEL-2664S can be applied with minimal need to modify existing generator protection and is ideal for all high-impedance grounded applications. The user can also inject up to four individual 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. The SEL-2664S is compatible with multiple communications protocols, including Modbus, DNP3, Telnet, IEC 61850, and FTP. The SEL-2664S offers one fiber serial and two fiber Ethernet ports along with two EIA-232 serial ports.
