Three phase transformers hold high importance in power systems. They have higher economic benefits than single phase transformers. They consist of three sets of primary and secondary coils, each set wound around a core made up of iron. These transformers facilitate proficient working of heavy machineries and let voltage transformation using less size, less material requirement, and less weight. The two types of construction method of three-phase transformer are single core and two cores. These construction methods can be further divided into symmetrical and asymmetrical. The type of connections used in these transformers are star and delta.
