A video on the back of my previous one which was taken down by request, exploring the basics of how transformers operate and their components and the most common causes of failure, and how we mitigate against that failure.
I’ll explore more specific concepts like harmonics and partial discharge in a future video as well as more on transformers.
My next video I'll pay more attention to the music / volume.

Correction:
01:00 This graph is parabolic not exponential. It's increase is quadratic.
02:31 The silicon steel is an alloy and the insulating layer between is typically a natural oxide layer but can be varnish or paper.
