Relay Field Engineer — West

Why This Role Exists Every protection relay and automation controller on a Tier III/IV data center must pass secondary injection testing before the system goes live — wrong trip timing or missed wiring means a failed witness test and a schedule slip. This role exists because our West Coast pipeline across California, Oregon, and Nevada needs dedicated device-level testing coverage on the ground. You test every relay and controller before energization. When the owner's witness testing coordinator asks for trip timing data, you produce it. What You Own Secondary injection testing for SEL protection relays — 50/51/50N/51N elements, trip timing verification As-found/as-left settings documentation for relay replacements and retrofits CT/PT ratio verification and wiring continuity checks from relay terminals to switchgear GOOSE subscription verification post-installation — publish/subscribe validation on PRP networks Trip timing measurement against coordination study curves FAT bench testing: DTSC-200 ATS controllers, relay parameter verification, I/O wiring validation Systems You'll Touch Vendor Platforms: SEL, Woodward, Omicron, Doble Software Tools: AcSELerator, QuickSet, Wireshark Protocols: IEC 61850 GOOSE Standards: IEC 62439-3 (PRP/HSR), NFPA 70E, IEEE 1584 Test Phases: Secondary injection testing, Factory Acceptance Test (FAT), Site Acceptance Test (SAT), Functional performance testing What Success Looks Like First 90 Days Performed secondary injection testing on SEL relays on an active West Coast project site Produced test reports in NETA/ANSI format with as-found/as-left settings comparison Demonstrated NFPA 70E compliance during energized MV switchgear testing First 180 Days Independently executing relay-level SAT on West Coast project sites Bench FAT testing for controllers (DTSC-200, easYgen 3400) with parameter and I/O verification Contributing to ZSI GOOSE functional testing on PRP networks Required Background 5+ years relay testing and electrical testing on medium-voltage power systems Secondary injection testing with Omicron CMC or Doble F6150 (or equivalent) Test report documentation per NETA/ANSI standards — as-found/as-left format Wiring verification: CT/PT ratio checks, continuity testing, relay-to-switchgear terminal verification NFPA 70E compliance: working on or near energized MV switchgear with arc-flash PPE Preferred Background NETA Level II or III certification SEL relay testing (AcSELerator QuickSet for settings verification) IEC 61850 GOOSE verification — Wireshark capture, publish/subscribe validation PRP network failover testing Based in or willing to relocate to Northern California or Pacific Northwest What to Expect in the Field Travel 40–60% during testing campaigns. West Coast sites (CA, OR, NV, WA, AZ). Site Hours: early starts for LOTO, occasional weekend milestones. Customer‑Facing Interface with prime contractor commissioning leads during witnessed testing. Documentation Heavy — test reports, as-found/as-left records, wiring verification checklists, trip timing data sheets. Field Safety: NFPA 70E compliance mandatory — arc‑flash PPE, approach boundaries, LOTO per relay position. Benefits (Why Ziggurat) Your test data proves the protection system works — settings, coordination curves, and GOOSE messaging validated by your measurements. Multi‑vendor relay testing: SEL, Woodward, CAT — broad platform exposure. Direct collaboration with the engineers who wrote the settings you test. West Coast data center growth puts you at the center of critical infrastructure construction. #J-18808-Ljbffr Ziggurat Automation Inc.
