It's truly awesome to see a couple of 16" diameter, 6' long carbon electrodes get plunged into a melting pot with an unbelievable amount of power connected to them at a steel mill. If a fella had his eyes closed and didn't know what was going on he'd likely swear that we were being attacked by Martians.
We have a railroad wheel manufacturing plant close by, Amsted Rail Griffin Wheel. Toured that plant with a group of teachers, back in the 80's. The electrodes were not quite as large as the ones Crusty described, but they had to contact the power company before energizing them so the power plant was prepared for the sudden HUGE load increase. I cannot recall the number MegaWatts, but it was very impressive.
The sound when they were energized was intense.
