Re: [TCML] PLAYING WITH HIGH-VOLTAGE WIRES, NO BIG DEAL

They're closer to cloth gloves. Unlike chain mail suits used by advanced Tesla Coilers, the suit, gloves, and socks these linemen are wearing are made from Nomex and microscopic stainless steel fibers. The suits are quite effective at conducting 50/60 Hz displacement currents at up to 765 kV lines. They reduce the "surprise factor" and discomfort from corona bursts and small streamers that can unexpectedly issue from elbows, toes, and fingers while the lineman performs live line maintenance on Extra High Voltage (EHV) lines. The Russians have used similar suits to perform live line maintenance on their 1150 kV system.
They are also not as effective as chain mail suits for Tesla Coil demonstrations. Many years ago, I watched as a volunteer, dressed in one of these suits, at one of D. C. Cox's Cheesehead Teslathons, became part of the topload of Cox's Big Bruiser coil. The suit material looks (and feels) like silvery-gray cloth. He had streamers coming from the fingers of his gloved hands and from the toes of the conductive socks on his feet. Although the suit was effective at conducting _some_ of the streamer current around his body, the volunteer was clearly feeling the effects of current leaking through the suit and then through his body, and he complained that his toes were getting burned. Following is some information about these suits from providers.

I would kill for one of these faraday suits!

Folks,

At the moderators discretion, Here is an interesting video of some
training for the power folks on a high tension line from a bucket truck.
I submit this because of all the discussion over the years on the effects
on taking sparks to the body and the possible ill effects that show up
later (joint ache, nerve damage, etc.).  I can only wonder if these guys
"feel it" the next day.
