The molecular level explanation of "cable burn-in"


According to one cable seller

"The insulation (or dielectric) will absorb energy from the conductor when a current is flowing (i.e. when music is playing). This energy-absorption causes the dielectric's molecules to re-arrange themselves from a random order into a uniform order. When the molecules have been rearranged, the dielectric will absorb less energy & consequently cause less distortion."

So it’s the plastic polymer (as dielectric insulation) to undergo some sort of molecular rearrangements to minimize the distortion. Probably one of the greatest scientific discoveries ever!

“Many premium AC cords constrict or compress the audio transient as their characteristic impedance restricts the transient current.”

We all know impedance restricts current but how possibly “many” premium AC cords constrict/compress the audio transient (when not carrying audio signal)? Then again is it achieved by this molecular rearrangements of the cable insulation?

Unfortunately there are no measurement data or mathematical formulas to be found to back up this amazing scientific discovery. Simply “it happens”. So I came up with a formula for them.

∆E = P - SoT

∆E: energy absorbed by dielectric

P: energy (power) drawn from wall outlet

So : Smake Oile

T: Dielectric Transition Temperature

If the wire is live there will be an electric field around it. That’s all that is needed, plus being held by the person checking for AC voltage. The person, being the ground completing a capacitive circuit.

How does a Volt Stick work?

More detailed, better explanation, than Fluke gives, imo.

The insulation covering a wire does not stop an electric field from passing through the outer wall of it. Nor will it stop an EM field from passing through the outer wall of it. A 100% shield around the live insulated conductor will.
