Rated Power

Rated power is the product of the rated output voltage and the rated output current.
In three-phase systems, it is calculated as the product of √3 times the rated output voltage times the rated output current, where the voltage is the line voltage.
If the transformer has more than one simultaneously loaded output winding, the rated power is the sum of the individual products.
If only one output winding is loaded, the product with the highest value is taken as the rated power. The same applies to taps. In three-phase systems, the calculation is done analogously.
