There’s a pole right next to my house. Like 2 metres away. Sometimes you can pick up on low pitched frequencies my wife has said the same thing? So has my neighbour? I don’t want to sound like a conspiracy theorist **** but something feels off in this house.. I will get an ECIR test this week is there anything I should ask the lad?
2+2=5, going slightly faint when standing up is a blood pressure issue. Nothing to do with EMI, otherwise National Grid workers on high voltage pylons would all be dead.
With twin cables (with or without earth) most radiation or pickup will be common mode. That's what the ferrite beads or rings are usually there to reduce. In principle it would work on separate L & N but these things are not designed for the sort of current you will get in a household mains supply.
They're normally installed to prevent common mode radiation or pickup. They act mainly to add a low value inductance into the circuit. So the answer is yes, in principle. But I don't know if you can get ones that will cope with the current likely on a household supply. I would guess not.
