functions.
- Configure and verify communication protocols including IEC 61850, IEC 101, IEC 104, Modbus TCP/RTU,
and Ethernet-based communication systems.
- Perform testing of bay-level control and interlocking schemes for breakers, isolators, earth switches,
and associated equipment.
- Perform loop checks and functional testing of measuring instruments and field signals where
applicable.
- Prepare and execute FAT, SAT, pre-commissioning, commissioning, and performance test procedures.
- Review approved drawings, protection settings, control schematics, logic diagrams, wiring diagrams, and project specifications prior to testing. - Prepare test cases, testing methodologies, inspection and test plans, method statements, and commissioning procedures. - Review and verify protection, control, relay, SAS, SCADA, and panel drawings prior to site execution. - Identify discrepancies between approved drawings and actual site installation and coordinate corrective actions. - Troubleshoot protection, control, communication, and automation system issues during testing and commissioning. - Coordinate with engineering teams for resolution of design-related technical issues identified during testing. - Coordinate with clients, consultants, vendors, construction teams, and subcontractors for testing and commissioning activities. - Prepare detailed testing, commissioning, FAT, SAT, inspection, and punch-list closure reports. - Maintain proper records of test results, relay settings, calibration records, test certificates, and commissioning documentation. - Provide technical support during energization, start-up, and handover activities. - Support retrofit, modification, upgrade, and replacement activities for existing protection and control systems. - Lead and guide testing technicians and junior engineers during project execution. - Ensure testing and commissioning activities are completed within approved project schedules and quality requirements. - Ensure compliance with applicable IEC, IEEE, NFPA, client specifications, and project-specific standards.
QHSE Responsibilities
- Ensure all testing and commissioning activities are carried out in accordance with applicable QHSE
standards, procedures, and project requirements.
- Ensure electrical isolation, LOTO, permit-to-work, and safe testing practices are followed before
commencement of testing activities.
- Participate in HAZID, risk assessments, toolbox talks, and site safety meetings as required.
- Prepare and review Job Safety Analysis (JSA), Risk Assessments, and Method Statements for testing
and commissioning activities.
- Ensure appropriate safety precautions are implemented during high-voltage and electrical testing
activities.
- Maintain proper test records, inspection documentation, and quality records for project traceability.
- Identify unsafe conditions and immediately communicate and rectify potential hazards.
- Support site quality inspections, NCR resolution, punch-list clearance, and final project handover.
- Participate in QHSE training programs, toolbox talks, and continuous improvement initiatives.
