Transformer Life Assessment






   With a proper condition assessment and maintenance program, power transformers can continue to provide reliable service far beyond the average transformer life expectancy. In fact, the use of aggressive asset management strategies is changing the way we view the expected lifespan of power transformers. It is a fact that some customers have power transformers on their systems that have been in service for over 45 years!


    Industrial Tests has a proven method for estimating the remaining service life of a transformer. This method builds upon a comprehensive condition assessment program based on IEC/IEEE standards. The process is designed to systematically identify changes in transformer condition. Adapted life assessment program can considerably reduce the risk of transformer failure and extend the life of your valuable capital assets.


    Our typical life assessment program for power transformer evaluation includes the following:

  • Review of historical test results and operating conditions,
  • Comparison of recent test results versus the historic results for the unit and similar designs,
  • Review of the OEM design and specifications,
  • Site inspection,
  • Electrical tests of the integrity of the transformer,
  • Electrical insulation quality tests for the paper and oil insulation systems,
  • A full battery of oil diagnostics,
  • Thermal analysis.
