FIELD: electricity.
SUBSTANCE: invention refers to transformer system (1) for electric arc furnace (2) with three electrodes (202) where transformer system (1) contains at least two three-phase transformers. Three-phase transformers (100) in this system are connected in parallel with electrodes (202) and are energised or respectively deenergised depending on each other and are operated synchronously.
EFFECT: increase in arc furnace power.
