Analysis of Interlocking Protection Circuit for Furnace Transformer
Currently, the company operates two electric arc furnace (EAF) transformers. The secondary voltage ranges from 121 V to 260 V, with a rated current of 504 A / 12,213 A. The high-voltage side has a total of eight tap positions, utilizing motor-driven off-circuit voltage regulation. The equipment is equipped with a reactor of corresponding capacity, connected in series to designated taps on the high-voltage side. These transformers have been in operation for over 20 years. Throughout this period,
