Transformer Preventive Maintenance Services

Our preventive maintenance program is designed to maximize transformer reliability, extend asset life, and prevent unplanned downtime. We service both oil-filled and dry-type transformers across utility, industrial, data center, mining, renewable energy, and oil & gas applications.

Scope of Services

  • Visual Inspections: Check for leaks, corrosion, abnormal noise, bushings, cooling systems, and grounding.
  • Electrical Testing: Perform insulation resistance, turns ratio (TTR), power factor, and dielectric tests to detect early signs of degradation.
  • Oil Analysis (for oil-filled transformers): Conduct Dissolved Gas Analysis (DGA), moisture content, and dielectric strength testing.
  • Cooling & Mechanical Systems: Inspect and maintain fans, pumps, radiators, and tap changers.
  • Documentation & Reporting: Provide detailed inspection reports, test results, and maintenance recommendations for asset management.

Benefits

  • Early detection of potential issues to avoid costly failures
  • Extended transformer service life and improved performance
  • Reduced downtime and increased system reliability
  • Compliance with IEEE, ANSI, UL, and NETA standards

Our experienced technicians provide on-site or shop-based preventive maintenance, tailored to the transformer type, operating environment, and criticality of your operations.
