Considerations on Direct Balancing of Ultra-High Power Ac Arc Furnaces in Uneasy State

Publication Date



The paper presents some observations and opinions for a discussion on a possibility of balancing ultra-high power ac arc furnace directly at the furnace terminals, i.e., on the secondary side of the furnace transformer. The negative effects of the furnace unbalance reveal themselves, first of all, in the furnace transformer. Therefore, balancing the furnace directly on its terminals could be beneficial for the transformer performance and, first of all, for reduction of the energy loss. Some technical issues have to be solved and several theoretical questions need to be clarified for that. Some of them are discussed in this paper.
