how to wire a three phase buck boost transformer?

To wire a three-phase buck-boost transformer, first ensure the power is off. Identify the primary and secondary windings on the transformer. Connect the primary side to the three-phase supply, ensuring correct phase alignment (L1, L2, L3). For the secondary side, connect the output terminals according to the desired voltage adjustment (step-up or step-down). Use appropriate wire gauges and secure all connections. Finally, verify the wiring with a multimeter before powering on the system.
