Sources Sought for SEL-387L

Notice of intent to use a brand name product. The Naval Facilities Engineering Systems Command, Pacific (NAVFAC Pacific) is performing a market survey to determine if other potential sources of supply can provide a transformer protection relay that has equal performance requirements as the SEL-387L, manufactured by Schweitzer Engineering Laboratories (SEL), 2350 NE Hopkins Court, Pullman, WA 99163. Fiscal Year 2027 SIOP PROJECT P-8026 ELECTRICAL BACKBONE Pearl Harbor Naval Shipyard and IMF Joint Base Pearl Harbor-Hickam, Hawaii, requires transformer protection relay that has equal performance requirements as the SEL-387L with the following characteristics: Line Differential Protection – Protect transmission or distribution lines using current differential protection for high-speed clearing of internal line faults. Provide dual-slope differential elements with external fault security and communications-assisted protection for internal fault detection while maintaining stability during external faults. Backup Protection – Provide comprehensive backup protection including phase, negative-sequence, and ground overcurrent elements, directional overcurrent elements, breaker failure protection, and configurable distance or permissive tripping functions as required for reliable line protection. Line Monitoring – Monitor three-phase currents, voltages (when applicable), frequency, power, sequence quantities, and communications-assisted protection status. Provide fault location and disturbance analysis capabilities to support system operation and maintenance. Reporting and Monitoring – Provide event reporting with sequential event recorder (SER), oscillographic event reports, fault records, and communications diagnostics to document faults, trips, currents, voltages, and relay operations for post-event analysis. Panel Control Switches – Conveniently sized operator controls shall be located on the relay front panel and configured to track associated operator control functions, including breaker control, relay status, and programmable pushbutton operations.
