Getting experts to agree on most things is challenging at best, and often,downright impossible. Getting transformer experts to agree might be even more challenging. Despite the fact that transformers have been around for nearly a century—and with varying opinions on transformer design and maintenance—most experts agree that not all transformer failures are alike. Also widely recognized is that the life of the insulation or paper is the primary limiting factor towards the life of the transformer. [Read more…]

Working in the reliability field with a focus on electrical systems, I have become increasingly aware of how many people believe in one or more of these myths and, more strikingly, stake their production uptime and even their career on them. I am not over-exaggerating. It is a big problem we seldom hear about because following these myths has led to a significant increase in the number of transformer failures with a corresponding dramatic increase in the cost of those failures.

So let’s get started. Be honest about it. If you know these are myths and are thinking the right way, then you will no doubt have just verified your prowess. On the other hand, if you believe some or all of these myths, then now is the time to recalibrate and set the record straight. [Read more…]
