I don't know if this has any application for you or not but here it is. I
have had ground loop problems between the power safety ground and the TV
Cable shield. I used two 300 to 75 ohm transformers and coupled their 300
ohm sides with 27 pf capacitors. I put them in an aluminum box with only
one of the shield sides connected to the box. It didn't degrade the picture
by any detectable amount and completely eliminated the hum that had resulted
from the ground loop.

Subject: [time-nuts] Noise and non-linear behaviour of ferrite transformers
Hi,
I'm currently looking at some way of breaking the ground loop between
several systems. The obvious idea would be to use transformers. I would
like to have some kind of rule of thumb to guess how much noise such
a transformer would add. But unfortunately i cannot find any theory
or measurements of this. Does anyone have some pointers to documents
on what kind of noise i could expect (type, and strength) and
what/how strong the non-linear behaviour of transformers would be?
Thanks in advance
Attila Kinali
PS: although this started as something with a real application in mind,
i'm now interested in this as an endavour of its own. So all and any data,
theory or rule of thumb would be appreciated
