What is the main purpose of a distribution transformer?

The main purpose of a distribution transformer is to step down the voltage of the primary mains to a usable voltage in the secondary mains. This is essential for delivering electricity to homes and businesses at a safe and functional voltage level. The primary voltage, which is typically much higher, needs to be reduced to a level that can be used by consumers, which is usually 120/240 volts in many regions.

Transformation of voltage is crucial in electrical distribution systems because it allows the efficient transmission of electricity over long distances by using higher voltages, while still ensuring safety and usability at the point of consumption. The redistribution of this energy through transformers makes it possible for various appliances and electrical systems to operate effectively without the risk of over-voltage that could damage equipment or endanger users.
