    we hijacked a conference room on a shared floor for a week and built a three-phase high-voltage line in there by hunting around the building for which sockets were on which phase, then plugging them into industrial transformers.

      Okay -

      • 1, that’s awesome;
      • 2, for what purpose?
      • 3, is it normal for buildings to have 3-phase in split into different single-phase sections? That feels like you could get some iffy stuff from wildly different loads on the different phases.

        we were recording the magnetic fields generated by a high-energy short circuit. we hung a mouse trap from one of the lines, with a lead going to one of the others, so that they fused together when it sprung.

        it is normal here, yes. larger appliances get three phases, and single-phase outlets are split between them as evenly as possible.
