mmmm, this thread is informative, jea48, please call me, if you recieved my #, I have done what you have specified, LOL!, everything in my house affects the sound of my sysytem, I have dedicated lines, I need dedicated breaker box with it's own ground for the system!, the ground is where this problem is, there is no other answer?
Does an isolation transformer improve a power cable?
In a post dated 12/14, I described how I built my DIY AC power cables. In evaluating these new cables over the first 100 hours, I am hearing parts in music I did not know where there--instruments are standing out in sharp relief with a more robust dynamic and improved clarity. All of this is coming through via Furutech's Ohno Continuous Cast copper, a brand I am not here to promote--rather, it is the one I chose to obtain a legitimate OCC material. These cables are feeding two ARC Reference 210's, modifed to 250's. But, what appears to make as important a contribution is what is feeding the AC cables their current--a large 240V/120V isolation transformer weighing 120 pounds and supplying 4000 watts of work to all of my devices via six outlets on the back. What I am understanding is that this thing provides a more ideal supply of current that is independent of the rest of the house and its appliances and devices. With all that is said about power cables and what they can and cannot do, depending on one's beliefs about alternating current, i.e., what is upstream, how could it matter, what about the rest of the grid, the last six feet is important, etc, I suspect that, in using a true induction transformer in this manner, the last six feet is the only six feet in my power supply, and this is why these OCC cables sound so stunningly good. Is this the purest AC energy pathway possible?

I wonder if anyone has converted 3 phase to a home use 120 line like this. I suppose that would even give better quality AC. Just to be a bit of naysayer/ clarifier the transformer does not "create" electricity as I have stated before. It is just isolating you from the grid from "quick" spikes and drops, any long term spike or drop will effect the other side of the transformer. The best way for clean AC is to have your own method of developing the AC signal from either using the grid power to DC and then back to AC or from off the grid sources as in solar and wind. The last two are becoming quite popular and should be able to create amazingly clean power (based on the inverter) |

Jea48, You are smarter than that. You know the definition of created. If the voltage on the supply side drops it drops on the other side of a transformer. It isolated electricity it doesn't create it. One side of the transformer has an electromagnet on it that created a field that oscillates at 60 hz. That field is transfered by the core to another set of wires that the field is inducted to. If electricity was truly being created, it would violate the first law of thermodynamics. Definition of a transformer: A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction.Transfer, not creation... Isolation transformers block transmission of the DC component in signals from one circuit to the other, but allow AC components in signals to passhmmm... so if I have an AC noise or change in AC voltage will the isolation transformer let it pass or will it always be a perfect sinewave? And for those that are excited about the idea of a balanced isolation transformer, from the NEC: 647.3 General. Use of a separately derived 120-volt single-phase 3-wire system with 60 volts on each of two ungrounded conductors to a grounded neutral conductor shall be permitted for the purpose of reducing objectionable noise in sensitive electronic equipment locations provided that the following conditions apply. |
