Hi Galen,
It’s been a while - greetings from HK! Trust that you and your family are all well and safe.
I wonder whether you could share your experience and knowledge regarding AC power cables as it pertains to BALANCED AC power transmission, specifically, with toroidal Balanced Isolation Transformers (BITs) which are well-known to offer the following benefits: 1) common mode noise cancellation 2) low pass filter (attenuation of uncorrelated high frequency noise 3) ground connection/pin isolation
As you well know, in a typical AC cable, there are three conductors - Live, Neutral, and Ground - individually insulated, loosely spiraled together, covered in an outer sheath, then covered with a braided shield.
What if we were to take the two AC conductors - Live and Neutral - and place them in a star-quad configuration, with the two individual conductors “split” into two, and then inserting the four conductors (and spiraled around each other) in a manner which resembles your Iconoclast XLR geometry - would this be optimal for the transmission of high voltage AC? Where would the remaining Ground conductor be placed in this star-quad example?
Would the center core of the star-quad cable be the “quietest” place, and hence the optimal place the Ground conductor should be placed, notwithstanding the certainty that this Ground conductor will be physically much shorter in length than the Live and Neutral conductors which will be spiraled in a larger diameter (around the center Ground conductor)? What would be the consequences of non-identical lengths of copper conductors between the Ground and the Live/Neutral?
Now back to my original question - if the AC being transmitted through the AC cable be “balanced” (ie. out-of-phase, with 60V in one conductor, and 60V in the other conductor, to sum up at the end to be equal to 120V), what would the best geometry of the conductors be, for lowest L, C, and R? Would the quad-core geometry (for unbalanced AC transmission) still be the most optimal?
