Someone I know who works at a steel plant says that you can wear 2 types of hearing protection (as is required around them) and still be deafened by it because of how it vibrates in your bones (and thus, your skull as well). It's also easy to misunderstand the tremendous size of these things, along with the gigantic amounts of power. The person I mentioned said anyone who wears any electronic device meant to keep them alive is ordered away from the electric arc furnaces upon starting them.

I'm guessing the big chunky cables on the right are powering the electrodes? I like how the first few times an arc is struck, you can see them sway a little bit. Assuming that is due to some intense electromagnetic fields forming and collapsing rapidly as tens of thousands of amps flow intermittently. I work around some big and powerful electrical equipment but nothing on this scale. Would love to witness this in person.

Most of the time yes it is with hydraulics.. although the factories in Russia and china typically utilize another system where there is a chain or a rope that leads to about 20 stationary bikes with pulleys and a bunch of chinamen pedal really fast when actuating the graphite electrodes. Usually, not always, one controls the switch gate, that’s what they call it, a switch gate and they can make the electrodes rise and lower

yeah haha the voltage is super low, i have litteraly measured that with a fluke 117 directly, i work as a regulation/measurement/automation maintenence person so when the electrodes don't wanna go down or "wiggle" up and down too much, they call me. Last time, the voltage measurement convertor (36v AC to 4-20ma DC) for electrode 1 had died, but I had to check the step down measurement transformer, so there I went and measured. Gotta love Fluke quality, and accuracy, you can measure those miliamps as well as those hundreds of volts. Of course you tell the operator to put the power to the lowest level first, you don't wanna play with that stuff :)

You only measure the output from the VT or CT (step down transformer), from both of them will be connected to the sensor transducer for measuring the current and the voltage, and most sensor the output will be 4-20 mA, it'll be feedback for the automatic regulation.
