Exceptions would apply if they run close to structural members, for instance if a transformer pad was on the same pad as your building foundation. I think that would be pretty odd, but some larger apartment complexes have their own mini substation/transformer inside them for residences. And, in busy/dense urban areas they tend to build substations into similar looking properties, e.g. there are some of these in London that hide infrastructure for the Underground.
I think it's important to make measurements of any noise before assuming this is the cause though. I'm still reasonably convinced this is psychosomatic -- that doesn't make it any less real to you but it means you won't fix it with a physical change unfortunately.

Transformers might be a different matter than cables. Transformers are designed to create a large magnetic field in their cores, and magnetostriction can translate that into mechanical vibration.
But the fundamental frequency for such vibrations would be 100 Hz -- hardly infrasound, biut well in the audible range. One might hear that frequency (and we all have, from small transformers, especially when they are not mounted well and transmit noise further). But it's hard to envision a scenario where one would feel the vibrations, and especially where one could feel them but without clearly hearing them too.

@lxmute, I sympathize with you and can relate to some extend.
In your quest to find the root of the problem you might find it, but keep in mind that when you are the only one experiencing it, getting a solution will not be simple. If it turns out to be a transformer station and you are the only complainer it is most likely nothing will be done about it. Then moving is the only option.
If it is something within yourself, then you might never find the root and then moving will not help either.
The latter is what I'm most likely experiencing. I'm diagnosed by exclusion with "chronic fatigue syndrome" with an emphasis on "fibromyalgia" which is a muscle disorder. For already twelve years now I'm also suffering from a "background hum" like a stationary tractor running next to the house. Sometimes it is louder then other times or even not there at all and the last couple of years I also feel small tremors that seem to coincide at the same frequency. Since I experience this everywhere I go and it disappears for a while when I take a warm bath, I'm pretty sure it is my own body causing it. For these symptoms there are no solutions found yet.
Boils down to that I just have to learn to live with it. I'm happy to still be able to do things like walking and small jobs around the house and my electronics hobbies. Others with this CFS disorder are wheelchair or bed bound.
My advise, do not obsess on it or it might drive you mad.

I agree. If you can't find a lot of other people complaining about it then it is very unlikely you can do anything about it. Even if you find a lot of complainers and figure out the problem and prove it is the problem and come up with a reasonable solution, it will still be very difficult to apply the solution.
If you move, you could find a bigger problem that affects more people and solve that instead. And you'll probably be a better problem solver at the new home since it'll be easier to think clearly.

Hello,
Big change happened this week. The Grid company made unwarned shutdown campaign on many transformers of the city during the night. I was already awaken by the stress by 4 AM. My PSU went ringing at around 5 AM. I had a 10min downtime. During that period all the stress vanished. My piezo sensors continued to record, some big changes, lowering all the noisy signal to nothing.
At morning a lot of citizens complained on facebook about hours of shutdown in their neighborhoods.
Asking them, the technical office of the city, told me that an exceptional operation of cuts on the transformers took place, in order to determine the source of a cabling defect.
A citizen told me he wasn't wired until 13PM and saw the Grid operators work on his transformer. Problem, that transformer is located 3km away from me.
Since I feel everything just different. Since, my infrasonic sensor stopped showing over-saturated patterns.

Sadly you still have not eliminated the psychosomatic incidence. You knew about the power cut.
Do you have trouble sleeping elsewhere?
Before you spend hundreds of euros more - maybe rent a hotel for one night near your home and one further away and note the quality of your sleep. I appreciate you know that you're somewhere else but you can try and see if you sleep more comfortably.
Ask a friend to sleep over when you're away and report any symptoms.
