Dry type transformer


True to its name, a dry-type transformer does not require fluid. It performs the same function as the transformer (converting electricity to usable voltages), but it’s better suited for low and medium voltage applications that don’t require as much cooling or dielectric strength. Typically you’ll see the dry-type transformer inside of your facility.


Failure modes

  • Insulation degradation due to moisture

  • Carbonization

  • Contamination


Reliability considerations

  • Power factor electrical tests

  • IR scanning (via IR windows)
