being in miami, finding old stuff is an extreme rarity. last storm season we found 3 transformers, reportedly in a crazy wye bank from 1923. theyre ge, 2 75's and a 100... im "shocked" we had 7620 back in those old days.
so it brings to mind, whats the weirdest system (utility supplied) you guys have ever worked on? 2 phase? dc distribution or transmission? any really odd ball voltages of standard connections?
