A transformer is only as strong as its weakest link | EEP

A transformer is only as strong as its weakest link, and the weakest link is the paper insulation, which begins to degrade around 100 °C.

Russ Roberts‘s insight:

A good, basic introduction to transformer ratings and maintenance.  The article stresses the importance of maintenance because large generator step-up devices (GSU) can cost up to one million dollars to build and up to 18 months to two years to be delivered to a site.  Since a GSU is built for a specific purpose, the failure of such a transformer could shut down a power plant for as long as 2 years.  Thanks to reporter David Hall for this story.  Aloha de Russ (KH6JRM).
