The Dangerous Task Of Repairing High Voltage Power Lines

Balls of steel!!
I'm not sure if this is of benefit here.
Were you not listening ? the electricity goes AROUND the Balls of Steel not THROUGH them. The frank and beans will stay golden.
That's what I mean, there's no point in having any special balls. It all goes around you, so they might as well be made of jello.

"So what are the consequences if this line goes down?"
"Load balancing."
thought that was good too

Warn for silly hard rock soundtrack.

Yep, that one's a lot more impressive. Also doesn't have the annoying narration trying to make it sound more dramatic.

The capacitors aren't the problem as stated above. The CRT itself is a very large capacitor (stores charge) and can knock you on your ass for a long time after the tv is unplugged.
Also, she's weird.
Yeah, my old boss got shocked by the CRT discharge and his arm swung against the side of the wall and he got cut really bad. It has about the same effect has getting shocked by an ignition coil from a car. I had a similar situation while working on a tube amplifier (around 600V).
High voltage DC will basically burn you really bad (provided it has enough current), but unless you have heart condition it probably won't kill you. It will defibrillate you and wake you up though.
High voltage low frequency AC (between 30 and 1000hz) is deadly starting at around 45 volts. As you get into the higher frequency AC voltages it has less affect on your heart, and thus less likely to kill you.
I saw a chart once in physics class that showed the lethality vs. frequency of AC. The peak was at 50 Hz--right where Europe put their power supply.
I got bit by 277VAC 50Hz once--burned a 1/2 inch hole 1/4 inch deep in my arm.
(I wish we had the metric system in the old USA)

Man in questionable safety gear is zapped with 500,000 volts
Artificial lightning generator in its normal time? High voltage testing? As long as he is electrically isolated from earth/ground he is perfectly safe as well. He probably could have gotten away without the mail since the sparks were from him being brought to potential... hes not conducting anything.
Fareed Zakaria--Global Warming Insurance

It seems to me that the super-heating of the ionosphere from Alaska with high voltage by the Navy and Raytheon may be able to convince the nay-sayers that the cause is man-made. "NEXT UP: Government declares rationing of oxygen for senior citizens AND, Sun taken in for questioning after extreme flare-up with third planet."
Subway Stops Inches Before Woman on Tracks
It amazes me how people don't die more often in subway stations: millions of people every day standing near a hole in the ground with high voltage electric rails, and a train comes by every few minutes to finish you off!
Arcing Powerlines Cause Tree Fire & Explosion
Wow, like really slow motion lightning (which also explodes some trees).
This is a good reason to always make underground power lines in urban areas. Where I live the only place with high voltage power lines is the countryside.
