FIELD: electrical engineering. SUBSTANCE: arc makeup current and recovery voltage at point of short circuit are corrected by inductive current for which purpose neutral of four-side reactor is unshorted. Additional capacitive correction of arc makeup current and recovery voltage is effected from emf sources of adjacent systems of phase disconnected during single-phase automatic reclosure cycle. EFFECT: improved safety of furnace during short-circuit faults. 3 wdgi
