Job Description – Protection Relay Programming & Testing Engineer Position

Protection Relay Programming & Testing Engineer – MV & LV Protection Systems

Qualification & Experience

• B.E./B.Tech. in Electrical Engineering.
• 7–12 years of relevant experience in protection relay programming, testing, commissioning, and protection/control systems.
• Predominantly experienced in MV switchgear, control and relay panels, and electrical protection systems.

Core Technical Expertise

• Hands‑on experience in protection relay programming, configuration, testing, commissioning, and troubleshooting for MV and LV protection systems.
• Strong experience with protection relays from:
  • ABB
  • Siemens
  • Schneider Electric
• Experience with platforms such as ABB Relion, Siemens SIPROTEC, Schneider Easergy/SEPAM, or equivalent.
• Strong knowledge of protection schemes including overcurrent, earth fault, directional protection, under/over-voltage, under/over-frequency, transformer, motor, and busbar protection.
• Ability to interpret SLDs, protection schematics, control schematics, wiring diagrams, and protection philosophies.
• Hands‑on experience in secondary injection testing, functional testing, trip testing, interlock verification, and end‑to‑end protection testing.
• Experience with OMICRON or equivalent relay test equipment is highly preferred.
• Experience in FAT, SAT, commissioning, site testing, troubleshooting, and final validation of MV/LV protection systems.
• Ability to verify relay settings against approved protection coordination studies.
• Preparation and review of relay setting files, test procedures, test reports, commissioning reports, and protection documentation.

Communication & Networking Expertise

• Strong hands‑on knowledge of industrial communication networks and complete communication topology associated with MV/LV protection and control systems.
• Practical experience with:
  • Modbus RTU
  • Modbus TCP/IP
  • Profibus
  • Profinet
  • Industrial Ethernet communication
• Strong understanding of IEC 61850 architecture, including IEDs, Station Bus, Process Bus, GOOSE, MMS, and SCL configuration.
• Ability to configure and troubleshoot communication mapping, data points, alarms, status, commands, measurements, events, and protection signals.
• Understanding of network switches, VLANs, IP addressing, gateways, network redundancy, and basic network diagnostics.
• Ability to troubleshoot communication issues across the complete chain—from protection relay/IED through network infrastructure, PLC/RTU, SCADA/EPMS, and higher‑level systems.

Control, SCADA & System Architecture

• Thorough understanding of the complete protection, control, and communication system architecture.
• Experience integrating protection relays with PLC, RTU, SCADA, EPMS/BMS, and other supervisory control systems.
• Ability to understand and review communication architecture drawings, network topology, I/O lists, signal lists, communication matrices, and cause-and-effect diagrams.
• Experience in FAT/SAT and end‑to‑end communication testing, including verification of commands, status, alarms, trips, measurements, events, and interlocks.

Desired Candidate Profile

The ideal candidate should be a complete Protection Relay Programming & Testing Engineer with strong hands‑on experience—not limited to relay software configuration.

They should be capable of independently handling the complete lifecycle of a protection system, including relay programming, protection setting implementation, logic development, secondary injection testing, functional testing, communication configuration, FAT/SAT, commissioning, troubleshooting, and final system validation.

The candidate should have a thorough understanding of MV protection systems, control and relay panels, protection coordination, industrial communication protocols, and the complete relay‑to‑SCADA/EPMS architecture.

Strong practical experience with ABB, Siemens, and Schneider protection relays, together with Modbus, Modbus TCP/IP, Profibus, Profinet, and IEC 61850, is highly desirable.

Experience in MV switchgear manufacturing, system integration, protection engineering, testing, and commissioning will be strongly preferred.
