RE: @Jea48: Single-family residential

I don't think anyone around me is doing anything crazy like a gi-normous ham radio set or anything like that, but it is a municipal electric company and I wouldn't be all that surprised to find out that they were putting a sh*tty product down their lines.


I would not blame the Utility company..... Probably as must as 80% of EMI/RFI/bad harmonics noise on the AC mains of a facility is created by electrical equipment and devices within the facility.

My questions were aimed as to the type of dwelling unit you lived in.
Example Hi-rise Condo? In the middle of a downtown city with commercial building all around. Or maybe you live on the fringe of a small industrial area. Bad harmonics can play havoc on electronic equipment.... Are you sharing a utility transformer with someone who is putting large amounts of EMI/RFI/bad harmonics back out on the mains?

Still, with a dedicated branch, re-grounding, an isolation transformer and a common-mode choke, how much recourse is left to try?

Explain the isolation transformer part in detail......
