====== 3 phase coupling ======

It is possible that powerline signal pass between phases using connected devices and crosstalk between wires.

But sometimes it requires capacitive coupling (1nF ?).

For devices powered from 3 phases without common neutral, special coupling circuit is needed:

MEDION
 najdluzsza linia - kuchnia - po roznicowce 1.8MB - zielone w spoczynku. pomaranczowe przy transmisji
 obok kuchni - bez roznicowki 7MB
  3 metry blizej - 6,1MB ???
  
  sypialnia - inna faza 3.37MB bylo czerwono ale przeszlo na zielone
  2.5MB - pomaranczowe
