Distribution transformers are generally used in electrical power distribution and transmission
systems. This class of transformer has the highest power, or volt-ampere ratings, and the highest
continuous voltage rating. The power rating is normally determined by the type of cooling
methods the transformer may use. Some commonly-used methods of cooling are by using oil
or some other heat-conducting material. Ampere rating is increased in a distribution transformer
by increasing the size of the primary and secondary windings; voltage ratings are increased by
increasing the voltage rating of the insulation used in making the transformer.
