Transformers at their practical best


Although transformers are very basic and static pieces of equipment and therefore tend to be very reliable if correctly designed, manufactured and applied to the designed application, the possible configurations are very extensive and complex.



Mechanical forces in a transformer can be large and the damage extensive under fault conditions (see example below). Purposeful design is crucial to the performance and lifespan of a transformer.


Take note

  • No electrical system could operate without the ubiquitous transformer.
  • The performance of a transformer is related to how it is designed and wound.
  • Never underestimate the complexity and importance of the transformer.
