The capacity specified on the transformer nameplate is the rated capacity, representing the situation when the tap switch is at the main tap, i.e., the product of rated no-load voltage, rated current, and the corresponding phase factor. For three-phase transformers, the rated capacity is equal to √3 times the rated no-load line voltage times the rated line current, usually expressed in kVA or MVA. The rated capacity is the maximum capacity that can be continuously outputted throughout the specified entire normal service life, such as 30 years. The actual output capacity depends on the voltage under load (in the case of inductive load, the voltage under load is less than the rated no-load voltage), rated current, and the corresponding phase factor.
