 No earpro or safety glasses, mower operator isn't wearing work boots and should also probably be wearing a hat to protect from the sun, un-attended child in the work area.

 quote:This lack of circulation in the cotton mills caused an epidemic of brown lung disease. People with brown lung feel like they are drowning when they lie down. It is very hot in this region in the summer, so families would put recliners on the porches so the people with brown lung could sleep at night. Though efforts to unionize at that point had been completely unsuccessful, some workers were able to make these "quiet sickness" signs to encourage people passing through to be quiet at night.

I need to check at work to see if maybe I could make a video like that. 120V: Runs normally 480V: Catches on fire(?) 600V: Catches on fire(?) 4160V: Catches on fire(?) Probably wouldn't be OK'ed. Anyways I was working at a place where we were taking apart some switchgear and there were sections where the unshielded high-voltage cables made contact with metal at the side/bottom of the cabinet. There were actually dark marks on the cabinet where corona discharge was developing through the cables. So you could see where the cables were touching the cabinet. So the lesson here is that at high voltages (>1000V or so) if you have unshielded insulated cables, you need to treat them as if they are bare. They cannot touch each other, and cannot touch metal surfaces. Otherwise you need to have shielded cables. Those are set up like this:

Hubis posted:What's the purpose or the semiconductor? Also, what semiconductor do you use? I'm only familiar with them in small electronic contexts (ie "wires, not cables") It's called a "semiconductor" but that's sort of a bad name for it. It's a material that's nowhere near as conductive as the actual conductor (copper or aluminum) but it's also doesn't have the extreme resistance as the insulator. The semiconductor fills in the gaps between the braided conductor and the insulator. This helps make sure the voltage is the same around the insulator. If you had a void or uneven surface, you may have a point where corona discharge could start damaging the cable. It's sort of like a pipe filled with a liquid at a high pressure, and making sure that pressure is even throughout the walls inside the pipe. Those layers have to be maintained when you splice two high voltage cables together, and properly tapered off when you do something like connect a high voltage cable to a termination or a busbar.

I'm only familiar with them in small electronic contexts (ie "wires, not cables") e: f;b Just read Three Phase’s answer since he works with this stuff regularly. “Semiconductor” is a bit of a misnomer here. It’s a nonconductive polymer mixed with a conductor like carbon. It has more in common with an antistatic mat than with a silicon wafer. The purpose of the semiconducting layer is to create a region of uniform potential around the cable to dissuade the electric charge inside from doing something like discharging to the ground (or to the shield) through the insulation on one side.

Platystemon posted:The purpose of the semiconducting layer is to create a region of uniform potential around the cable to dissuade the electric charge inside from doing something like discharging to the ground (or to the shield) through the insulation on one side. Yeah and that's bad, since in a proper installation the shield is grounded. I think that with that sort of thing you get a cascading failure - current flow through that fault would rapidly increase. The more current flows the more the insulator is damaged. The more the insulator is damaged the more current flows. Some of these high voltage systems are delta-connected so there's no significant reference to ground. So if that happened you'd need a set of potential transformers set up to detect that a ground fault had occurred as minimal current would flow. (Or with a resistive-grounded wye, you'd have neutral current flowing through a huge resistor to ground, limiting the current to a thousand amps or so. Enough to trip protection but not enough to blow equipment apart.) That's getting a bit technical... (It's nice to have some secondary verification in case we missed something here.)

Specifically PCs are capable of doing a range, if you look on the back it'll probably be fine to plug it into whatever (for a laptop), or there's be a switch on the PSU to swap between 110 and 240 for desktops. Just read the small prints. More generally, for bigger consumer products you'll get a fat rear end transformer that weighs five+ kilos and is the size of a shoebox.

Household appliances should be replaced instead of shipped over. Down-stepping converters have a power limit anyway.

It is 60hz in North America and 50hz in Europe. So an adapter or power supply has to deal with that also.

The label on the PSU or transformer/wall wart will tell you if it will auto-switch or not (most can). If it's unclear, manufacturer's spec sheet online should let you know.
