Powervar/OneAC and Ground question

dm · « **on:** 31 Jan 2004, 01:59 pm »

Currently I have all of my equipment plugged into the same outlet. I do not have any ground loop issues since they all share a common ground.

If I get one of thes isolation transformers and separate off some of my digital gear onto the new oneac/powervar, am I not introducing the possiblity of CREATING ground loop or at least ground differential problems since electrically the front end equipment will still be connected to the isolated backend equipment thru interconnection cables and their shields?

Help me understand how this works....thanks.

You should not have any problems. A larger 220V/110V ONEAC has a patented "virtual ground" feature which isolates the building's ground from the transformer's.

You are referring to what oneac calls "virtual kelvin ground" or thier "oneground technology" feature? The oneground is optional and not on all models.

That's right. You can find them in eBay. I have a 3KW CB2338 and it works very well...

A lot of noise comes up through the ground. There is this brand of expensive Swiss high end equipment whose transformers isolate the ground. If you can find one for a decent price, go for it. I got mine for $100.
