Cpl is the best way to have a lot of unnecessary HF throughout the house
other detail this HF does not pass in the winding of the meter or differential circuit breaker: it does not leave the house
it does not go from one phase to another: problem for home powered by three-phase
some remarks also on the CPL.
I had the opportunity to test with a member of the criirem http://www.criirem.org/ the EM radiation of the CPL. It's almost zero, compared to WIFI, DECT or GSM, or even a low consumption light bulb (like, 1000 x less) it almost merged with the "background noise".
Similarly, regarding the meters, my neighbor has cpl 85 mps, old standard (not encrypted), when I arrived in my house, I received his CPL instead of mine with my cpl adapters of different brand, but of the same standard .
A friend had the same experience in his apartment, plugging a cpl into an outlet in the hallway, and it worked very well.
Conclusion: it depends on the electrical installations.
Finally, I confirm the problem for three-phase. If we have no problem, it is because all the sockets are on the same phase.
However, there are materials allowing the cpl to go from one phase to another, a phase coupler (between 20 and 150 €: conrad.fr/coupleur_de_phases_pour_prources_powerline_p_49300_49300_857062_857063
)
And always: use a biplite instead of an extension strip, see the new cpl with pull-out socket
