Project Description: The Government intends to procure, under only one responsible source, where no other suppliers or service will satisfy the agency requirements. The Naval Facilities Engineering Systems Command, Hawaii (NAVFAC Hawaii) is conducting market research to determine if other potential products/services can provide a transformer protection relay that has equal performance requirements as the SEL-787, manufactured by Schweitzer Engineering Laboratories (SEL), 2350 NE Hopkins Court, Pullman, WA 99163. The alternate product/service must meet the following requirements/specifications:

Provide transformer protection relay with the following capabilities:

▪︎ Transformer Protection - Protect transformer using differential elements for tripping for in-zone faults. Two-winding dual-slope differential protection with harmonic blocking and restraint, and phase, negative-sequence, residual-ground, and neutral-ground overcurrent elements provide backup protection.

▪︎ Overcurrent Protection - Provides complete overcurrent protection for a two-winding transformer. Including a complete set of phase, negative-sequence, and residual overcurrent elements for each winding

▪︎ Transformer Monitoring - Use transformer through-fault monitoring to measure accumulated through-fault levels of the transformer. Monitor ambient, load tap-changer (LTC), tank, and transformer oil temperature through the use of optional 4–20 mA or RTD thermal inputs.

▪︎ Reporting and Monitoring – Provide sequential recorder to document events such as faults, trips, voltage, and current.

▪︎ Panel Control Switches - Conveniently sized operator controls shall be located on the relay front panel, and set to track operator controls.

This notification is for market research purposes only and should not be construed as a commitment of any kind by the U.S. Government to issue a solicitation, request for proposals, quotes, or invitation of bids or award a contract.
