Relay Settings Engineer
Location: US (Remote)
About the Role
Join a dynamic team of industry experts driving grid reliability, protection system performance, and regulatory compliance. As a Relay Settings & Protection Engineer, you will play a pivotal role in designing, setting, testing, and commissioning relay protection systems for high-voltage substations across our transmission and distribution networks.
What You'll Do
Relay Settings Development & Testing
- Create and review protection settings for transmission and distribution substations, including:
- Line distance, bus differential, transformer differential, and breaker failure protection (e.g., SEL-311C, SEL-411, SEL-487, SEL-451, GE B90, GE T60).
- Distribution protection schemes (feeder overcurrents, underfrequency load shed, transformer differentials).
- Design and validate communication-assisted schemes (POTT, DCB, line differential).
- Troubleshoot custom relay logic and coordinate with SCADA/RTU systems.
System Modeling & Analysis
- Model protection systems in ASPEN OneLiner, CAPE, and other analysis tools.
- Conduct fault studies, coordination studies, and time-current curve (TCC) analysis.
- Analyze relay event data (e.g., SEL SynchroWAVE) for post-event reliability improvements.
Compliance & Standards
- Ensure compliance with NERC standards (PRC-002, PRC-004, PRC-005, PRC-027).
- Support audits and develop documentation for regulatory requirements.
- Serve as the subject matter expert for compliance reporting and record-keeping.
What We're Looking For
Minimum Qualifications:
- Bachelor's Degree in Electrical Engineering or related field.
- Engineer-In-Training (EIT) certification (or Professional Engineer license preferred).
- 3+ years of experience in relay settings development and protection system design.
Desired Experience:
- Hands-on experience with SEL relays (SEL-351, SEL-451, SEL-501, SEL-311C, SEL-411, SEL-487) and GE protection devices.
- Proficiency in:
- ASPEN OneLiner
- CAPE (APA) System Modeling
- SynchroWAVE, Powerbase, PSS/E
- Experience with event analysis, digital fault recorder systems, and compliance reporting.
- Knowledge of substation design standards and control schematics (DC, AC, and one-lines).
