how to wire a transformer 3 phase?

To wire a three-phase transformer, first identify the primary and secondary windings. Connect the primary side to the three-phase power source, ensuring correct phase alignment (A, B, C). For a delta connection, connect each phase to the corresponding winding. For a wye connection, connect one end of each winding to a common neutral point. On the secondary side, follow the same configuration as the primary. Always ensure proper grounding and adhere to local electrical codes for safety.
