how to wire a 3 phase step up transformer?

To wire a 3-phase step-up transformer, first ensure the power supply is disconnected. Identify the primary and secondary windings on the transformer. Connect the three-phase input wires to the primary terminals, following the correct phase sequence (A, B, C). For the secondary side, connect the output wires to the load or distribution system. Ensure proper grounding and use appropriate fuses or circuit breakers for protection. Always follow local electrical codes and safety standards.
