What influences the power of a transformer? How is the power calculated?
The power of a transformer is mainly determined by the dimensions of the core and the steel-plate material. The size of the core comprises the yoke size, limb size and layer height. Another important factor in configuring the power of a transformer is the ambient temperature in which the device is to be operated. From an electrical point of view, the power output (in VA) is calculated from the product of output voltage Ua and load current Il to ohmic load.
