The analog meters show volts amps at transformer primary. Later the screen shows secondary V A in red green blue vertical bars. 270 to 300V phase-ground, up to 50,000A each phase. This furnace is in USA. Primary? 34,500V phase to phase 19,900V phase to ground. Transformer is delta primary, Y secondary. Must be dedicated 34KV line for this factory. 34KV line feeds substation 1½ blocks from here. 2400/4160 Y secondary serves neighborhood. Voltage usually very steady here but not @ factory

@a380rockerfan 16.8MVA is nothing. There are ones which run over? 100MVA.

looks like it´s out of control and will? explode every moment :D

@kaaitj They are multiple 1600mm² cables feeding each electrode. Look under my EAF busbar? video which gives you an idea of the TX side buswork.

How thick are those? wires (in mm²) that feeds those arcs?

dam that must be a big transformer, haha? i need one, never seen this video untill now, place looks like fun, love the video man

Damn, i wanna see the transformer that powers? this thing!

youre? job is deuce

@jmartis2 - Actually, I am correct. VA, while affected by reactivity is a separate measure. Regardless of how many inductors, capacitors, etc you put in a circuit or how you modify the phase, VA is VA. This is because DC has a stationary wave form so it's? power factor is constant. 10vdc*10a=100W period. 10vac*10a*cos?=70w. This is because AC voltage changes with the waveform. :)

@1krr Nope, you have both W and VA in an AC circuit and they are the same only for unity power factor. When the power factor is less than 1, the V * A is less than W in the circuit. This might be caused either by reactive power (capacitive, inductive) which results in a phase difference in V/I, and/or a distortion of their waveforms. For example when you connect a capacitor to an AC source, it draws? amps, there are volts of it but the watts are zero.

@denelson83 - A voltamp (VA) is a measure of power, like a watt, but in an AC circuit. In AC the voltage is constantly changing between a postive and negative value which means the circuit is only at peak power for a fraction of total time where a DC circuit stays at the same voltage. So the difference just allows one to compensate for that fact. ?

@RODALCO2007 What's the difference between a VA and a Watt??

@HugMyNutz When nothing? is happening.

how do you know if something has? gone terribly wrong?

my car did? that once

The energy is so immense, I find it to? be beautiful :p

i would like to see a gauge that shows rotor torque at the power station. If they generate their own power on site does anyone know if they use big flywheels or? anything of the like to help maintain the constant operating speed of the generator?

@a380rockerfan 40 MVA?
By: a380rockerfan. on 18 Oct 11, 08:08:17
42kA * 400v = 16.8 MVA output. That is a LOT of power! How big is? the furnace transformer?

@femix26 Intense, very hot and extremely noisy Thanks for? your comment.
By: femix26. on 22 Sep 11, 08:18:00
Been working around EAFs 20+ years and never a dull? moment, lol. This is one of the better vids I've seen, gives a pretty good idea of how intense steelmaking is, but as most will agree, nothing compares witnessing it in person.
By: RODALCO2007. on 21 Sep 11, 06:30:40
@yourTIV0? Those arms are hydraulic controlled and lifted and lowered to maintain a steady arc. Especially when not all steel has melted a lot of movement is visible.
