Job Summary:
We are seeking a Relay Setting Engineer with 3–4 years of experience in HV/EHV substation protection systems for US-based utility and EPC projects. The role involves relay settings development, protection coordination studies, relay communication, and integration of relays with Substation Automation Systems (SAS)/SCADA. Hands-on experience with SEL and GE (Multilin) relays is mandatory. Familiarity with US standards such as IEEE, NEC, and NERC guidelines is required.
Key Responsibilities:
– Develop and validate protection relay settings for HV/EHV substations (69 kV, 115 kV, 138 kV, 230 kV, 345 kV, 500 kV).
– Perform protection coordination studies using Excel, Mathcad, and ASPEN OneLiner.
– Design and review protection schemes for transmission lines, transformers, feeders, and busbars.
– Configure relays using SEL AcSELerator QuickSet and GE EnerVista software.
– Work with SEL RTAC for relay communication, data concentration, and control logic implementation.
– Prepare relay settings calculation reports and documentation in MS Word.
– Support relay testing, commissioning, and troubleshooting activities.
– Verify protection schemes including breaker failure, auto-reclosing, and interlocking logic.
– Review SLDs, schematics, and wiring diagrams.
SCADA / Substation Automation Responsibilities:
– Integrate protection relays with SCADA/EMS/DMS systems.
– Configure and validate IEC 61850 (GOOSE, MMS), DNP3, and Modbus communication.
– Perform signal mapping, I/O checks, and database validation.
– Develop and validate communication schemes using SEL RTAC.
– Coordinate with SCADA teams for alarms, controls, and data acquisition.
– Support end-to-end communication testing.
Technical Skills:
– Strong understanding of HV/EHV protection schemes including distance, differential, busbar, and transformer protection.
– Knowledge of breaker failure protection, synch check, and auto-reclosing.
– Hands-on experience with SEL and GE Multilin relays.
– Experience with SEL RTAC configuration and relay communication.
– Familiarity with fault analysis, ASPEN OneLiner, and disturbance record review.
Software Skills:
– SEL AcSELerator QuickSet
– GE EnerVista
– SEL RTAC configuration tools
– ASPEN OneLiner
– MS Excel, Mathcad, MS Word
Standards & Compliance:
– Knowledge of IEEE protection standards
– Familiarity with NEC (National Electrical Code)
– Understanding of NERC PRC standards (PRC-001 to PRC-027)
– Exposure to utility-specific practices (e.g., PJM, ERCOT, CAISO is an advantage)
Additional Requirements:
– Experience with EPC/utility transmission projects in the US.
– Understanding of CT/PT selection, protection class, and grounding practices.
– Experience with testing tools such as Omicron or Megger (is an advantage).
Soft Skills:
– Strong analytical and problem-solving skills
– Effective communication and reporting skills
– Ability to work independently and collaboratively
