How many times have you been electric shocked? and do you remember the voltage?
<< < (4/6) > >>

Quite a few times on 240 volts. Those were when I was much younger. Once, many years back, from a Sony color TV which threw me across the room. Most recently had 10kV from the scope while configuring the new tripler. Just forgot that I had turned it turned off a minute before!

Made me jump, but to my surprise, and that of the neurophysiologist, after 5 fingers had been done, I came over faint. Heart palpitations, dizziness, and severe shortage of breath (all I could do not to rip off my surgical mask). Never had that before, on the odd occasions, many years ago, when I hit a finger with 240V. I have low blood pressure for my age, but I guess it got a bit too low.

That's made me cautious: fortunately I don't do any high-voltage work, except maybe for repairing power supplies. I think I'm going to give that up though, and buy new replacements in future - but there's always something they don't make any more, or charge a fortune for...

P.S. No sign of Carpal Tunnel Syndrome! :)

Take care morden guys.

To be honest, your special experience makes me think about purchasing a Ergonomic Mouse

Nobody want to be shocked by 400V pulse, and a doctor, with smile face, tell you before every shock,
"Take this shock agian. It's good for you!" :-[

Reminded me....  :-DD

when you power on this device, does those electical equipement, which surround your attena such as computer, mobilephone etc. could work as usual as normal, 
and could you feel hot or faint?

The linear amplifier was connected to a shielded dummy load so there wasn't much radiation to affect other equipment.

Besides, this all took place 45 years ago so we didn't even have computers, cellphones or similar to be affected by the transmitter!

Quite a few times with 240 volts. Back in the late 80s and the 90s I was a commissioning engineer for large UPS systems so mains voltages were ubiquitous throughout the equipment and sometimes, even when you thought you were careful, shit happened. The systems also used DC voltages at around 500 volts, with some units with voltages up at around 900 volts but with those I always tread very, very carefully and thankfully never got a belt from that.

My worst experience was getting 415 volts from forearm to forearm. Completely my fault. I'd come in on a Saturday morning at a client's site to do some work on a 400 kVA UPS. I'd transferred the site load across to maintenance bypass, shut down the UPS, and then switched off the supply to the UPS. Or at least I thought I had. I wasn't thinking, I was a bit hungover, and failed to realise that even though the screen on the UPS was dead that this unit was dual fed and I'd only turned off one of the incoming supplies. I reached around some three phase busbars and managed to contact the outside two bars with my forearms. I was thrown a few metres back and was stopped by a wall. The site manager was looking at me ashen faced but I told him I was OK, went outside and sat down for ten or so minutes - or two smokes worth - and then went back inside and continued to work. The stupidity of youth.

I still remember my first.  Back in 1965, I was a 13-year old newly minted ham radio operator with my first transmitter, an Eico 723 60 watt crystal controlled CW unit.  The final amplifier, 6DQ6B, needed to be neutralized.  I didn't have much in the way of tools back then, so my only choice for a thin blade screwdriver was an all steel butter knife out of the kitchen drawer.  Well, the knife slipped as I was adjusting the capacitor and went right onto the plate of the tube (while the transmit key was down).

Gave me such a zap, that my hand jerked backwards, I let go of the knife, and it sailed across the room and stuck into the wall.  A one-in-a-million shot!  Probably about
400 volts @ 150 ma on the tube.

Many more shocks since then, but like sex, you always remember your first.
