A distribution power transformer is a stationary electrical device that is used to transform an alternating voltage (current) of a certain value into another voltage (current) of the same frequency or different values. When the primary winding is energized with an alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux is magnetically conducted through the iron core, so that an alternating electromotive force is induced in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary winding, i.e. the voltage is proportional to the number of turns.
