The place and place for installing the distribution transformer, namely the substation. A distribution power transformer is a stationary electrical device that is used to transform an ac voltage of one magnitude to another voltage of the same frequency or different magnitudes. 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. The main role is to transmit electrical energy, and thus, the rated capacity is its main parameter. The rated capacity is a conventional value for the power delivered, which is characteristic of the amount of electrical energy transmitted, and is expressed in KVA or MVA, from which the rated current is determined, which does not exceed the temperature rise limit under the specified conditions, when the rated voltage is applied to the transformer. The power transformer with relatively low energy consumption is amorphous alloy iron core distribution transformer and has the greatest advantage of extremely low no-load loss value. Whether the no-load loss value can be ensured finally is a core problem to be considered in the whole design process.
