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.
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.
First off, instead of using bullets and then manually enumerating then, try putting "1. " at the the start of every item in the list. Don’t increment the “1”.
Around me the only homes without 3phases are older small apartments. Most houses have a 35A 3phase supply, although 63A may become the norm on account of EVs. It’s quite normal to have a 3 phased fuse where each phase is used for something different. Say a fuse box is used for lighting and outlets, but L1 is ground floor, L2 is upstairs and L3 is outdoors.
BTW if you ever move into a house where someone has put outdoors on the same rcd as the rest of the house, then do yourself a favor and get a separate combo rcd/fuse for outdoors. When the rcd trips, it’s always the outdoor usage, and it sucks when all the lights go out, because a gasket died in an outdoor lamp.
From your comments it sounds like this is Europe? In the US, 3-phase residential is rare - usually limited to large apartment buildings.
Usually what we have is a “split phase” system, where it comes in at 240v and a local ground is used to divide it into two 120v legs.
BTW if you ever move into a house where someone has put outdoors on the same rcd as the rest of the house, then do yourself a favor and get a separate combo rcd/fuse for outdoors.
It varies by state, but some states have requiring outdoor outlets to be on a separate breaker or GFCI (RCD) outlet already, for just this reason.
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.

Okay -

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

Did you build Tesla coils or something? Were there intentional sparks involved?
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.
