Electric Arc Furnace Regulation

Write, e-mail or call the maker of the furnace and ask for the calibration instructions.

Or, just turn it on and see what happens.

Or, just turn it on, ^{_{STAND BACK}} and see what happens.

Getting someone else to turn it on is much safer.

I will trade you an apple . . .

No thanks, I know what happened last time an apple was offered.

Upon start-up, the electrode will run in to strike and retract to a balanced point. There has to be a fine adjustment to trim for optimum arc. You may also have to adjust the anticipator.

I think Lyn has your best choice so far. Yo do not say if it is an AC or DC unit or the type of regulator your using. There are many companies that provide these services for folks such as your self. It also is some thing you should not be doing unless you know what your doing. You can do a lot of damage to the equipment in a big hurry. Read Gary Bakers book on Furnace regulation, good info!

Thanks for all of your answer,

@fixitorelse : I'm sorry I didn't describe the detail about the furnace, it's an AC furnace feed of from 60/66MVA transformer with Voltage Rating : 30kV/490-850Volt and Current : 1307-1800/63500-80000A. I'm interested in your suggestion to read "Gary Bakers book on Furnace regulation", but I can't find the book. Can you please tell me more detail about the book? Like the title and the publisher, a link if possible. Thanks.

@all : I'm just curious I have been reading some article and one of the article said that the good Z in transformer secondary (Line power to furnace) is the same as the Ztransformer. Than I remember about maximum transfer power that will happen when the Zin = Zout, where in this discussion. Zin = Ztransformer and Zout = Zactual = Zset.

And what I was thinking is that, the transformer I used is still the same an has no change, so having the transformer secondary (Line power to furnace) change (ex. The conducting arm), really does't effect in the change of Zset because you want to set the Zset to be same as Ztransformer.

How about your though? Sorry for my bad english >Z<
