Transformers are designed for long operating life, but failures can occur.
Common causes include overheating, insulation breakdown, excessive vibration, moisture exposure, overloading, and installation issues.
Heat remains one of the biggest factors affecting transformer life. Excess temperatures can degrade insulation materials and shorten lifespan.
Mechanical stress and repeated environmental exposure may also affect long-term reliability.
Understanding failure causes early helps engineers improve designs and avoid recurring issues.
Preventative testing and proper design margins remain key elements in long-term success.
