Executive - Relay Testing

Role & responsibilities

Job Purpose

We are looking for 4 to 5 Years of experience in Numerical Protection Relay Testing with strong electrical engineering fundamentals and hands-on experience in testing and commissioning of numerical protection relays, protection logic, IEC 61850 communication, SCADA integration, and substation automation systems. The candidate should have a good understanding of power-system protection, relay characteristics, protection schemes, communication protocols, and end-to-end substation automation testing.

Key Responsibilities

1. Perform functional and secondary injection testing of numerical protection relays.

2. Test and validate protection functions such as Overcurrent, Earth Fault, Under/Over Voltage, Frequency, Directional, Differential, Distance, Breaker Failure, Auto Reclose and Synchro check.

3. Verify relay settings, pickup values, operating time, trip characteristics and accuracy.

4. Test and validate relay logic, trip/intertrip, blocking, permissive, interlocking, alarms and control functions.

5. Perform binary I/O and end-to-end functional testing of protection schemes.

6. Hands-on testing of IEC 61850 MMS, GOOSE, Reports, Data Sets and Logical Nodes.

7. Validate GOOSE publish/subscribe, status, quality, timing and communication between IEDs.

8. Understand and work with ICD/CID/SCD files and IEC 61850 station configuration.

9. Perform SCADA/HMI integration testing, including status, analog values, commands, alarms, events and SOE.

10. Participate in FAT, SAT, commissioning and site testing activities.

11. Troubleshoot relay, communication, logic and integration issues.

12. Strong knowledge of Power System Protection and Electrical Engineering.

13. Hands-on experience with Numerical Protection Relays and secondary injection testing.

14. Good understanding of protection schemes, CT/PT, circuit breakers and SLDs.

15. Strong knowledge of IEC 61850 and GOOSE testing.

16. Knowledge of SCADA and Substation Automation testing.

17. Experience with relay testing tools such as OMICRON CMC/Test Universe, DOBLE 6150 or equivalent.

18. Knowledge of IEC 61850 diagnostic tools will be an advantage.

19. Knowledge of IEC 60870-5-101/104, Modbus, DNP3, PRP/HSR and time synchronization will be an added advantage.
