What type of transformers provide power to smaller entities such as factories or residential areas?

Distribution transformers are specifically designed to deliver electricity to smaller consumers, such as residential neighborhoods and factories. These transformers step down the voltage from the higher levels used in transmission systems to levels that are safe and usable for local distribution.

Their role in the power system is critical, as they ensure that electricity can be utilized effectively at the local level. Typically, distribution transformers are located near the end-users, minimizing energy losses that can occur over longer distances. They usually operate at lower capacities compared to other transformer types, making them ideally suited for local distribution needs.

Subtransmission transformers, on the other hand, are used for the further distribution of power from high voltage transmission lines to substations but do not serve users directly. Power transformers are used in generating stations and substations to step up or down high voltages, while line transformers are specialized transformers that can also step down voltage for specific applications but are less common in the broader distribution network context.
