Kapanadze and other FE discussion

Hi Wesley my friend, I did already quote you this here earlier, I believe, directly from the Tivar product literature, but here it is again:
"The incorporation of an effective carbon black grade renders this material electrostatic dissipative properties."

As I said before, it has carbon in it to give the material its *conductive* anti-static properties.
If the material wasn't conductive to high voltages it would be useless as an anti-static material for floor mats or whatever else.

Again, as I have explained, the material may well be plastic coated to give it a very high resistance to lower voltages
(rendering it as an insulator as a floor mat for example if someone accidentally touches voltages such as 120V or 220V),
but high voltages will easily jump across the thin insulating plastic coating and dissipate through the conductive carbon
in its interior, allowing it to work as an effective anti-static material.  Those Tivar blocks in strong (high voltage) electric fields
are almost like blocks of conducting metal. I would guess that if you puncture the Tivar material with some pointy multimeter probes
and measure the resistance that way that it may well register as a quite low resistance, not that I am asking you to damage
your Tivar blocks if you don't want to. All the best...

 Corona  seen on conductor in Tesla coil has nothing to do with dielectric.
There was no single piece of wire or any conductor.


This part of a  big slab is totally dielectric  and anti-static and uniform in its consistency.
Surface wave is giving you HV charge on the surface of dielectric.
Surface of dielectric is the interface with air.
In contrast to it the wood below can not serve as lossy  conducting medium as it is not conducting.
Earth is used as returned wire for HV and LW power networks.
The  difference between surface of dielectric is that at frequencies  higher than approximately 52MHz  uneven surface    cancels continuity of the surface  wave.
With earth however there is a need for proper resonant transformer  to be able to receive the surface wave.
In addition  I was in Near Field and that can explain sparks in my mouth.

Hi Wesley. I haven't worked with that specific material before, but I know well the reason
it has carbon infused into the material (gives it its dark black color). The carbon is in there
100% for certain to make the material conductive to high voltages. The carbon may possibly be
interspersed thoughout the material with other substances in such a way that gives it a high resistivity
to lower voltages (say less than 500V) even in its interior, but for absolute certain that material
is conductive enough to high voltages or it would be completely useless as an anti-static material.
To continue to deny something that obvious would be completely ridiculous.

Also, it absolutely would not show high voltage corona discharge between the Tivar blocks if the
material was not at least somewhat conductive to high voltages. It doesn't take super high conductivity
in a material for it to conduct a significant current when a high voltage is applied across it. That Tivar
material with the carbon compound in it is very clearly conductive enough to high voltages to act as
an effective anti-static material, or they most definitely wouldn't be selling it as such, and also as seen
in your video screen shot, to allow corona discharge to occur between the two blocks of Tivar.

Carbon is a quite a good conductor, especially when high voltage is applied across it. If you have any doubts,
please look it up, and please do contact the manufacturer of those Tivar blocks and ask them why the material
has carbon in it, and ask them what that Tivar material's conductivity is when subjected to very high voltage.

Quadrant EPP TIVAR® DrySlide UHMW-PE, Lubricant Filled, Electro Static Dissipative
UHMW-PE

Redco™ Ultra High Molecular Weight Polyethylene (UHMWPE) has extremely low moisture absorption, a very low coefficient of friction, is self lubricating and is highly resistant to abrasion (10 times more resistant to abrasion than carbon steel). Redco™ UHMW has the highest impact strength of any thermoplastic presently made and is highly resistant to corrosive chemicals, with an exception of oxidizing acids.
Redco™ UHMW plastic is known for its durability, machinability, versatility and cost-effectiveness. Virgin UHMW is FDA compliant and is used in applications where high levels of friction are likely to arise including chain channel, wear strips, belt scrapers, guides, and rollers. Redco™ UHMW can be machined into virtually anything from small bearings to large sprockets and liner systems. Due to an extremely low coefficient of friction, its inherent lubricity minimizes friction resulting in a smooth, noiseless operation.
Outperforming and more cost effective than metal in many applications. Redco™ UHMW is highly durable and available in a wide variety of formulations and grades.

here you have its electric properties based on American standards. D257
Nothing you say is found here.
this is American product not some of Far  East, Eastern European  garbage
