The distribution or step-down transformers are the preferred choices of transformers for the commercial and residential industry. Considering that, both the transformers are used to scale down the heavy voltage-current produced at power stations into the voltage levels usable in the buildings or residential surroundings.
For residential purposes, single-phase transformers are recommended by power transformer manufacturers. They supply the low-voltage current for efficient operations of household appliances and equipment - residential fixtures of lighting, Air-conditioning, heating needs, receptacle, etc. Furthermore, to increase the productivity of such transformers, their manufacturers prefer constructing the primary and secondary windings in two equal parts.
On the other hand, commercial transformers are used to supply the power of the required voltage current, for smooth and lasting operations of the electrical equipment in the building. It also serves the purpose of reducing the distribution voltage of the building to an adequate level. The ones aid smooth functioning and ensure the right amount of power supply, as consumed by different equipment.
