Advantages of Three Phase Transformer over Single Phase Transformer

by

Three Phase Transformer Generally, electrical energy is generated in generating stations by 3-phase alternators. 3-phase system is used for transmission and distribution of Electric-energy. For stepping down or stepping up the voltage of these systems, 3-phase transformers are used. Advantages of 3-Phase Transformer over 1-Phase Transformer (For Same Capacity) Q. State the advantages of three … Read more
