Losses and optimization measures in transformer operation?

Transformers will face various losses during operation, including iron loss and copper loss. In order to reduce these losses and improve efficiency, we can take a series of measures such as optimizing the selection of core materials, reasonably designing the coil structure, and strengthening heat dissipation to ensure that the transformer can work efficiently and stably and extend its service life.
(1) Iron loss is caused by the iron core. When the coil is energized, the magnetic lines of force are alternating, which will generate eddy current and hysteresis losses in the iron core. This loss is collectively referred to as iron loss.
(2) Copper loss is caused by the resistance of the coil itself. When current passes through the primary and secondary coils of the transformer, power loss will be generated. This loss is called copper loss.
The sum of iron loss and copper loss constitutes the total loss of the transformer. These losses are closely related to the capacity, voltage and equipment utilization of the transformer. Therefore, when purchasing a transformer, the equipment capacity should be matched with the actual usage as much as possible to improve equipment utilization and avoid light load operation of the transformer.
