How is ideal grounding achieved for a whole house?
I know the usual techniques used, but I’m sure some perfectionists who know what they’re doing have installed groundings that are a whole lot better…
Even a certain person has each of his 9 sockets used for audio grounded separately, each with its own dedicated line. He said the grounding rods are at a circular array so as to avoid magnetic issues, he stated… Not sure of those separate grounds due to ground potential differential, BUT he has low interwinding capacitance isolation transformers for this purpose, apparently?
Does a high quality (as in, very low interwinding capacitance, etc) isolation transformer eliminate the ground differential noise issue?
Please discuss this in detail.
