Why This Role ExistsEvery 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 OwnSecondary injection testing for SEL protection relays — 50/51/50N/51N elements, trip timing verificationAs-found/as-left settings documentation for relay replacements and retrofitsCT/PT ratio verification and wiring continuity checks from relay terminals to switchgearGOOSE subscription verification post-installation — publish/subscribe validation on PRP networksTrip timing measurement against coordination study curvesFAT bench testing: DTSC-200 ATS controllers, relay parameter verification, I/O wiring validationSystems You'll TouchVendor Platforms: SEL, Woodward, Omicron, DobleSoftware Tools: AcSELerator, QuickSet, WiresharkProtocols: IEC 61850 GOOSEStandards: IEC 62439-3 (PRP/HSR), NFPA 70E, IEEE 1584Test Phases: Secondary injection testing, Factory Acceptance Test (FAT), Site Acceptance Test (SAT), Functional performance testingWhat Success Looks LikeFirst 90 DaysPerformed secondary injection testing on SEL relays on an active West Coast project siteProduced test reports in NETA/ANSI format with as-found/as-left settings comparisonDemonstrated NFPA 70E compliance during energized MV switchgear testingFirst 180 DaysIndependently executing relay-level SAT on West Coast project sitesBench FAT testing for controllers (DTSC-200, easYgen 3400) with parameter and I/O verificationContributing to ZSI GOOSE functional testing on PRP networksRequired Background5+ years relay testing and electrical testing on medium-voltage power systemsSecondary injection testing with Omicron CMC or Doble F6150 (or equivalent)Test report documentation per NETA/ANSI standards — as-found/as-left formatWiring verification: CT/PT ratio checks, continuity testing, relay-to-switchgear terminal verificationNFPA 70E compliance: working on or near energized MV switchgear with arc-flash PPEPreferred BackgroundNETA Level II or III certificationSEL relay testing (AcSELerator QuickSet for settings verification)IEC 61850 GOOSE verification — Wireshark capture, publish/subscribe validationPRP network failover testingBased in or willing to relocate to Northern California or Pacific NorthwestWhat to Expect in the FieldTravel 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
