I think the question was meant as a joke, as it is called "galvanic
isolation".
Almost 20 years ago, an international group of engineers that made up
the Working Group of which I was Vice-Chair went around about
"galvanic isolation" while writing AES Standards for EMC. The result
of our discussions was that the term had no real meaning because no
one could produce a real definition for it in the literature.
Likewise, NR1DX was right to question "Ohmic Isolation."� If we mean
DC isolation, we should say so. If we mean that there is a two-winding
transformer to minimize common mode current, we should say that. Too
many words like "ground" and "balun" have multiple meanings -- they
are confusing, obscure how things work, and cause people to do the
wrong things to solve problems.
