Akarakara Structural 
Nke ochie nke akarakara ordinary transformers, arc furnace transformers enwere ike ịkpọta special requirements of steelmaking processes, including a certain overload capacity and mechanical strength against short circuits.

The regulation methods of arc furnace transformers are divided into two types: on-load voltage regulation and no-excitation voltage regulation. Arc furnace transformers with on-load voltage regulation are not equipped with series reactors.

Arc furnace transformers with no-excitation voltage regulation have two structural forms: those with series reactors and those without. Both structures can change impedance at the maximum secondary voltage. The former changes impedance by switching the series reactor on and off, while the latter changes impedance by altering the connection mode of the high-voltage windings of the arc furnace transformer itself.
