Technical specifications include kVA/MVA rating, primary and secondary voltages, vector group, frequency, cooling class (ONAN/ONAF/ODAF), impedance, losses, insulation level/BIL, tap-changer type, temperature rise, bushings, protection accessories, and applicable standards (IEC/IEEE). Specs define how the transformer integrates into a grid or industrial system and set procurement and testing requirements.
