Jun 11 2005 · 12 Jun 03 20 24. I work in a structural steel mill which uses a DC Electric Arc Furnace (13.8 kV). We have been having problems for quite some time with the electrode arcing to the furnace roof and damaging the water cooled panels. I am currently researching ways that I can electrically isolate the roof from the body of the furnace.
