To make the transformer connections compatible with three-phase supplies we need to connect them together in a particular way to form a Three Phase Transformer Configuration. The combinations of the three windings may be with the primary delta-connected and the secondary star-connected, or star-delta, star-star or delta-delta, depending on the transformers use.

Pad-mounted transformers for distribution systems typically range from around to kVA, although some larger units are also used. Use ring-terminal crimp lugs and machine screws on connection tangs, with quarter-inch Belleville washers to compensate for the varying thermal expansion of different conductors.

If you were to connect the two output wires directly together, that will constitute a short circuit and cause far too much current to flow in both the primary and secondary and you will burn out the transformer.

Please fill all fields. Transformer Wiring Diagram B. Distribution transformers are made using a core made from laminations of sheet steel stacked and either glued together with resin or banded together with steel straps.
