    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.

        Sounds like an industrial setting, they typically get three phases. Probably also explains the desire.

        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.

        no, and yes. i’m not going into more detail for fear of doxxing myself but basically we wanted the waveforms generated by a high-voltage short circuit.

        later tests involved help from a power company and actual high-voltage lines.
