• Carry out commissioning and testing of high‑voltage (HV) equipment and systems under the guidance of senior engineers or commissioning leads.
• Support pre‑commissioning and commissioning phases for substations, transformers, switch gear, and protection systems.
• Perform HV testing activities such as:
  • Primary and secondary injection testing of protection relays
  • Contact resistance (Ductor) and insulation resistance testing
  • AC dielectric withstand tests
  • CT/VT ratio, polarity, and burden checks
  • End‑to‑end scheme verification and functional testing
  • Transformer ratio, winding resistance, and polarity tests
• Assist with system energisation and handover, ensuring all test results and documentation are accurate and complete.
• Contribute to FAT, SAT, and site commissioning activities, identifying technical issues and supporting their resolution.
• Maintain up‑to‑date test records, commissioning schedules, and documentation in accordance with project requirements.
• Promote safe working practices on site and ensure compliance with Health & Safety procedures.
• Work closely with design and protection engineers to review relay settings, logic configurations, and coordination requirements.
