Relay Field Engineer — Southeast

ZA-33009 - Charlotte, NC (Field)

Hiring ENG III

• 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 switch gear
• GOOSE subscription verification post-installation — publish/subscribe validation on PRP networks
• Trip timing measurement against coordination study curves — confirming relay behavior matches design intent
• FAT bench testing: DTSC-200 ATS controllers, relay parameter verification, I/O wiring validation

• SEL
• Woodward
• Omicron
• Doble

• AcSELerator Quick Set Wireshark

• IEC 61850 GOOSE

• IEC 62439-3 (PRP/HSR)
• NFPA 70E
• IEEE 1584

• Secondary injection testing
• Factory Acceptance Test (FAT)
• Site Acceptance Test (SAT)
• Functional performance testing

• Performed secondary injection testing on SEL-751 or SEL-700G relays on an active project site
• Produced test reports in NETA/ANSI format with as-found/as-left settings comparison
• Demonstrated NFPA 70E compliance practices during energized MV switch gear testing

• Independently executing relay-level SAT on project sites — secondary injection, wiring verification, trip timing
• Bench FAT testing for controllers (DTSC-200, easYgen 3400) with parameter and I/O verification
• ZSI GOOSE functional testing: blocking signal verification and selective trip timing across PRP networks

• 5+ years relay testing and electrical testing on medium-voltage power systems
• Secondary injection testing with Omicron CMC or Doble F6150 (or equivalent) — trip timing, coordination validation
• Test report documentation per NETA/ANSI standards — as-found/as-left format
• Wiring verification: CT/PT ratio checks, continuity testing, relay-to-switch gear terminal verification
• NFPA 70E compliance: working on or near energized MV switch gear with arc-flash PPE

• NETA Level II or III certification
• SEL relay testing (AcSELerator Quick Set for settings verification)
• IEC 61850 GOOSE verification — Wireshark capture, publish/subscribe validation
• PRP network failover testing
• Woodward DTSC-200 or easYgen 3400 bench FAT experience

Travel 40–60% during testing campaigns. Southeast region primarily (VA, NC, GA, TN, FL).

Site

Hours:

Site hours during testing: early starts for LOTO, occasional weekend milestones. Off-hours for energized testing windows.

Customer-Facing Interface:
With prime contractor commissioning leads during witnessed testing; site safety coordination.

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 (Cat 2+ for MV), approach boundaries, LOTO for each relay position, daily safety briefings.
