Air Core Reactors
Electric Arc Furnace Reactors

More efficient operation of Electric Arc Furnaces will be achieved by increasing the source impedance of the EAF’s power supply in order to optimize their melting process.

For this purpose dry type reactors (buffer reactors) are connected in series to the primary side of the furnace transformer. Commonly these reactors are tapped, typically covering a range from 40 % to 100 % of the rated impedance.
