200 kVA – 10 MVA10 kV

Induction melting draws a rough, harmonic-rich current through a rectifier front end. A 12-pulse transformer reduces the harmonic content injected into the supply compared with 6-pulse arrangements, and the winding and cooling design is matched to the furnace duty cycle rather than a steady load.
