If you’ve been following this blog for a long time, you know that we dealt with transformers a lot. This topic is interesting and much requested so we did our possible to add more publications about it.

Steven Mill, one of our active members, chose to talk about the role of cooling in the life of a transformer. You can check his essay below…

As a result, the devices in enclosures overheat, they breakdown and make you spend a lot of time and money in fixing your mistakes. Your clients are dissatisfied and endure operating losses that can reach several millions of dollars in some sectors.

Faced with this issue, the worst solutions are: to install a cooling system at random, using the one you use for all your machines from habit, or simply to not install a cooling system at all.
