Fiscal Year 2027 SIOP PROJECT P-8026 ELECTRICAL BACKBONE Pearl Harbor Naval Shipyard and IMF Joint Base Pearl Harbor-Hickam, Hawaii, requires the following characteristics. Provide protection system relay with the following capabilities: Feeder Protection – Protect distribution feeders using phase, ground, negative-sequence, and sensitive ground overcurrent elements. Provide instantaneous and time-overcurrent protection with configurable directional elements to detect and isolate feeder faults while maintaining system coordination. Breaker Control and Protection – Provide breaker failure protection, autoreclosing, synch-check (when required), trip circuit monitoring, and integrated breaker control functions to improve system reliability and minimize outage duration. Feeder Monitoring – Monitor three-phase currents, voltages, frequency, power, power factor, demand, and sequence quantities. Provide fault location, metering, and power quality information to support system operation, maintenance, and troubleshooting. Reporting and Monitoring – Provide Sequential Events Recorder (SER), oscillographic event reports, fault records, and relay diagnostics to document faults, trips, breaker operations, currents, voltages, and relay performance 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 open/close control, relay status indication, and programmable pushbutton operations.
