Not a "problem". Some weird fault in the network could affect the whole neighborhood. I can't bother reading the thread again, but did anyone ever put an oscilloscope on the electrical signal? If there were bad disturbances or phase shifts, it could in theory cause machinery doing weird stuff, causing even more disturbances. It is beyond me, though, how a human could detect it, but it sounds like in this case it has also caused physical disturbing phenomena, like vibration, infrasound or some such.

At the moment I just feel good *again* in my home. Standing on the floor doesn't provide any stress. Which is my only goal in this weird story.  It feels "empty" of something that became a "daily dose" during 4 years. Watching again RaspiBoom datas tonight, I'm prone to confirm everything's changed.

As someone wrote earlier, a trouble miles away can emerge at a particular spot. Maybe some sort of "barycentric" equilibrium between transformers like I asked about. I'm not qualified enough on high power domain and tricks to judge.
Anyway.. I really really really hope the current working state will remain stable.
I just feel some slight shake at my desk (what I would qualify as "transient noise" feeling), 2 meters and a wall near of the bend of 3x3-phase cables.

For the tip about renting a place elsewhere. I experienced same feeling, with slight differences 5km away. It was starting 5AM. I experienced it 300km away as well, 30m near of a transformer, 1st floor, but slept well in that same city, in another hotel, 10km north, 6th floor. This sensibility is like a 6th sense.
last singularity: In my garden I have 2 desert tortoises. Then are older than me. Over those 4 years I saw them behave differently than 42 years before. I saw them tense, sleeping in places in the garden where they had never slept before, letting themselves be exposed to the weather in the middle of winter when they were protecting themselves before to hibernate. Letting their legs hang out of the shell while they never did that. In the end, very close to what I was trying to produce myself in my habitat.
Weirdy.. not that weird to my experience.

So what should I conclude ? Some dumbass contractor plugged a 3 phase cable into the ground and it was just leaking during 4 years? Arriving by a vein of water in the moats of my medieval district? Is it possible ? Since I'm not on the side of the Grid Company's knowledge, I can just formulate an hypothesis. The shutdowns and operations recently made, semt to solve the problem.  :-+ :-+ :-+

Hello,
some fair amount of time have passed. I wanted to gather what I consider to be important facts before going further on that (somehow extra-)ordinary topic.

I recently had a talk with an electronic engineer, he gave a look at my building, and noticed a fundamental and problematic fact: the three-phase cable from power company touches my building gutter, made of zinc-galvanized steel.
Taking a EF meter, and scanning the gutter, I have E field going up to 350V/m. If I take the gutter on the opposite side of the building, E's right at 0V/m.

I went further also with audio microphone, infrasounds, and seismic sensors, getting phased recordings. Some B+A.sin(w.t) sinewave close to 25Hz.
Taking a BPM app, tapping on it in rythm to the feeling of spikes, reversing the BPM, I end up with 0.83Hz frequency. I have just graphical view of that wave, yes I should dig further into data analytics and numpy to find the exact values, but it would mean I'm flickering between 25Hz (+/- 1Hz) and 25.83Hz. I have scanned all acoustic footprints of my devices at home and find nothing corresponding to that 25Hz device.

Could it be a link between both of them ? Lorentz force is able to move cables. What would be the power going through a cable to mark a slightly micro vibration ?

If you actually had an E-field of 350V/m, this would be comparable to standing next to an operational television transmitter.  You would suffer generally serious side effects, far beyond some quality of sleep issues.  I suspect your meter is faulty or you are misreading it.

Did the engineer concur with your measurement... and are they a qualified engineer?
JohanH:
In general, metal pipes and other metal structures in a building should be grounded by connecting them to a common ground point (usually at or nearby the incoming electrical service panel), which is connected to a ground rod. Not many connect objects such as gutters and roof (might be different legislation in different countries also), but it is beneficial that every metal object is grounded. If it's done as a lightning conductor, roof and gutters should have copper cable into the ground in each corner of the house, that is then connected to a common ring around the house. If it's for grounding in general, they should be connected to the common point where the house otherwise has it's main incoming electrical panel and ground rod. This way there will be no induced electrical fields in the metal objects.
