Sources Sought SEL2731

The Naval Facilities Engineering Systems Command, Pacific (NAVFAC Pacific) is conducting a market survey to identify potential sources of supply for a transformer protection relay with equal performance requirements as the SEL-2731, manufactured by Schweitzer Engineering Laboratories (SEL). The required product should have the following characteristics: industrial Ethernet communications, network management and security, time synchronization, network monitoring, and substation integration. The notification is for market research purposes only, and responses should include detailed technical data for the Government to conduct a comprehensive evaluation of the manufactured product. • The product should support managed industrial Ethernet switch to support reliable communications between protective relays, automation controllers, SCADA systems, meters, and other intelligent electronic devices (IEDs) within the substation network. • The product should support managed network functions including virtual local area networks (VLANs), Rapid Spanning Tree Protocol (RSTP), port monitoring, traffic prioritization, Simple Network Management Protocol (SNMP), and user authentication to ensure secure, resilient, and maintainable communications infrastructure. • The product should support Precision Time Protocol (PTP) transparent clock functionality, Network Time Protocol (NTP), and other time synchronization methods to provide accurate event time-stamping and coordination of protection and automation devices. • The product should continuously monitor switch status, communications links, network performance, and diagnostic information, and generate alarms and event logs for communication failures, port status changes, and network faults to support system maintenance and troubleshooting. • The product should support integration with substation automation and SCADA systems through industry-standard Ethernet networking technologies and protocols, providing reliable communications for protection, control, monitoring, engineering access, and system diagnostics.
