Power factor correction is based on the LOAD reactance. If it is reactive, the apparent power and the reactive power aren’t close, we need to add capacitors to the system such that the power company no longer sees the reactive power WITH the “used” apparent power. This puts a lot of stress on the power plant. The cable’s resistivity doesn’t really matter except it won’t waste apparent power in the lines with low DCR “wires”.
The capacitance is the dielectric of the space between plates or wires. Even if we had an invisible wire in there, the AIR is the dielectric. If we have a super wire, it’s dielectric properties will produce the capacitance.
The classic formula for capacitance is define by “e” permittivity and distance “s” in this example. “R” isn’t a thing yet for capacitance.
Capacitance equation
How to calculate the capacitance, then? You need to use the following formula:
C = εA/s
where:
C is the capacitance. It is measured in farads (symbol: F);
ε is the dielectric permittivity (a measure of resistance) in farads per meter;
So then …how does the SR graphene employed in the line of fuses create
such an improved sq…Is it the black dot on the fuse body or is the graphene
employed in the fuse wire itself?
Here’s what I found about Graphene on the net. It’s a rare earth metal that is 200 times stronger than steel, 100 times stronger than diamonds, and 1000 times more conductive than copper. I don’t know how much of that is true.
While what you point out is true, Graphene is technically a Carbon allotrope of single atoms arranged in a planar honeycomb shape. It can be folded into 2 and 3 atom “thicknesses” where the alignment of the planes is offset by some degrees. The “magic” 1.1deg fold of the 2 plane is what has been shown to exhibit the superconductivity we have been discussing. Here’s a cool website for anyone interested in Graphene and its applications from a reputable source Applications - Graphene - The University of Manchester
Other than SR, Zavfino also uses graphene as the shielding layer for their top Silver Dart OCC lines. I currently have two of their power cords and they are doing a great job of lowering the noise floor. So at least two companies are utilizing this material for their cables.
moving the offending source, or recipient, of the hum is by far the best option - unless the source is huge and outside the house already - the inverse square law is your friend
