it's a small to mid sized basic Tesla coil, (not a Van de Graff generator). The tesla coil generates massive voltages that easily exceed the breakdown voltage of air. It would seem that the folks at SR are using the cable under test to connect the target ground point (the thing the spark discharges to) to ground via the unit under test (the cable). The high frequency ( >100kHz + harmonics) voltage pulses will no doubt cause an effect to the dielectrics of the cable, but will they last...?
It would seem they refer to this method of dielectric change as quantum tunneling...big words for a very simple phenomenon. Very nice video. Love the ceiing vent.
By the way if anyone is remotely interested in sending me their cables for the ultimate tunneling job I can hook them up to my jumbo bug zapper, or a pimped out neon sign transformer to about the same effect. Just bend over and wire the money first.
