Testing & Commissioning Engineer (HV Substations)

Job Purpose

As a Testing & Commissioning Engineer (HV Substations), you will play a pivotal role in ensuring the seamless execution of high-voltage (HV) and extra-high-voltage (EHV) substation projects. Your primary responsibility will involve conducting comprehensive testing, commissioning, troubleshooting, and energization activities to validate system performance, adherence to project specifications, and compliance with stringent safety and industry standards. This role demands a high level of technical expertise, meticulous attention to detail, and the ability to collaborate effectively with cross-functional teams to deliver projects on time and within budget.

Key Responsibilities

In this dynamic and challenging position, your core duties will include:

• Substation Testing & Commissioning: Execute pre-commissioning and commissioning activities for HV/EHV substations ranging from 13.8kV to 380kV, including power transformers, GIS/AIS switchgear, circuit breakers, disconnectors, earthing switches, current transformers (CTs), voltage transformers (VTs/CVTs), protection & control panels, SCADA systems, and communication networks.
• Protection & Control Systems: Conduct rigorous testing and configuration of protection relays, secondary injection, and primary injection tests to ensure optimal performance and reliability of the substation’s protection schemes.
• Transformer Testing: Perform detailed transformer testing, including turns ratio (TTR), winding resistance, insulation resistance, and functional tests, to verify operational integrity and compliance with technical specifications.
• System Verification & Troubleshooting: Validate interlocks, control logic, and protection schemes to identify and resolve potential issues during commissioning. Provide expert troubleshooting support to address equipment and system anomalies, ensuring minimal downtime and maximum efficiency.
• Energization & Synchronization: Support critical energization and synchronization activities, ensuring that all systems are safely and efficiently brought online while adhering to project timelines and safety protocols.
• Documentation & Reporting: Develop and maintain comprehensive commissioning procedures, test reports, and punch lists. Prepare and submit daily, weekly, and final commissioning reports to stakeholders, ensuring transparency and accountability throughout the project lifecycle.
• Stakeholder Collaboration: Work closely with clients, consultants, and project teams to facilitate smooth commissioning activities, address technical queries, and ensure alignment with project objectives and client requirements.
• Safety & Quality Compliance: Uphold the highest standards of safety and quality throughout all testing and commissioning activities, ensuring full compliance with regulatory requirements, industry best practices, and organizational policies.
