• 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
+ IEC 61850
+ 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.

He 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.
