The point I failed to make is because I brought a machinists understanding to an electrical engineering conversation. I assumed a specific definition of the word "standardized" that isn't common to electrical engineering. Here's what I should have said.... What's needed is standardized, interchangeable transformer modules. We need to be able to parallel as many of them as we need to manage a load, and if one dies, swap it out with a new module, possibly 30 years later, with NO need for adjustment. Just as precision makes it possible to deliver parts that fit within 100 microns from countries on the opposite sides of the globe (and has for almost a century thanks to Johansson[1]), we should be able to produce a standard, easily paralleled transformer module that can simply be bolted to others to match situational requirements. Bolting in a new module shouldn't result in the need for balancing or any other adjustment, the parts should just work together. This would have helped immensely in Ukraine, for example... as missile damaged sections of a transformer stack could be individually replaced, instead of the whole thing. There are enough CNC tools and measurement techniques in the world to make this possible, we just need to make it happen.
