There are already standardized transformer sizes(e. g. 40MVA). Electrical transmission is pretty standardized already IMO.

- mschuster91 4y agoThe problem is that large scale transformers are expensive to produce which means that it makes no sense to keep stockpiles for a disaster case. Usually that calculation works out, as most electricity grids, even on the low-voltage distribution level, are meshed enough to tolerate one or sometimes two large-scale transformers going offline. You get into problems though if more of these transformers go offline - e.g. because someone shoots them with rifles or artillery - because the lead time is weeks to months. And completely forget about a nuclear EMP scenario... it would probably take a decade to recover from that.
- WJW 4y agoTransformer protection equipment is quick enough to disconnect them in case of an EMP, it's usually the control electronics that are identified in vulnerability studies as the weakest link. Those have a much shorter lead time than the multi-ton copper parts and are also much easier to have a stockpile of.
