Transformer Supervisors – Oil Filtration

Operational Responsibilities

• Supervise transformer oil filtration, dehydration, and degassing activities.
• Ensure proper setup and operation of oil filtration machines (vacuum type / high‑vacuum plants).
• Monitor oil parameters such as BDV (Breakdown Voltage), moisture content, acidity, and IFT.
• Maintain required oil temperature and vacuum levels during processing.
• Ensure correct connection of hoses, valves, and filtration units to avoid contamination or leakage.
• Coordinate oil filling during transformer installation or maintenance.

• Enforce safety procedures and permit‑to‑work (PTW) systems.
• Ensure use of PPE (gloves, goggles, safety shoes, etc.).
• Follow electrical isolation and lockout/tagout (LOTO) procedures.
• Prevent oil spillage and ensure environmental compliance.
• Ensure adherence to company standards and client specifications.

• Conduct pre‑and post‑filtration oil sampling and testing.
• Verify oil meets required standards (BDV value, moisture ppm, etc.).
• Maintain filtration logs and test reports.
• Ensure filtration continues until oil achieves acceptable parameters.

• Lead and guide technicians and operators.
• Allocate tasks and monitor workforce performance.
• Provide on‑site training for safe oil handling and filtration procedures.
• Coordinate with site engineers and project managers.

• Inspect filtration machine condition before operation.
• Ensure timely replacement of filters and maintenance of vacuum pumps.
• Troubleshoot operational issues during filtration.
• Maintain tools and equipment in good working condition.

• Prepare daily progress reports.
• Record oil test results and machine parameters.
• Report any abnormalities in transformer condition.
• Submit final completion report after filtration work.
