Application Of Three Phase Transformer
Shell-type 3-phase transformers are three separate 1-phase transformers. Each of these three phases has its own magnetic field, which makes this type of transformer's core five-limbed. The high voltage and low voltage windings are around the three main limbs. The two outermost limbs serve as the flux return paths. 3 Phase Transformer Configurations
