EAF

What thread below?

the link/url i have given I hope you understand now

Well, it may go fine with you but do realize that process requirements have to be precisely catered, better option was to find out the real cause of tripping.

Wish you good luck.

I think we had this discussion awhile back on the EAF tripping. I still suggest that you find someone to come and look your unit over, that knows what their doing. Before you cause harm to your self on the equipment by adding something on that does not belong there.

The EAF installed around 1973.That is before my birth.So i don't know initial performance of the furnace.Our managers and engineers know well about the furnace. We have decided to introduce this circuit in the amplidyne controlled furnace by comparing the performance of it with a thyristor controlled furnace. In thyristor controlled furnace we have an automatic arrangement for lifting electrode more than normal operating speed.when the current signal exceeds 4.6Amps that is 125% of normal operating current there is a sudden lift of all three electrodes bringing decreased current level in power circuit. There is a special relay for this task in the thyristor board.
