Back To Basics

Transformers are all around you. They come in a wide range of shapes, sizes and application purposes. To get a general idea of where transformers are used, let’s look at a simple electrical utility system.

Figure 2. Simple Distribution System

Once electricity is generated, the voltage is increased by transformers. It is then transported to substations, where transformers decrease the voltage to usable levels for industrial plants, shopping centers and homes. These large amounts of electricity are moved at high voltages for a number of reasons, such as lower losses of power and overall Efficiency. The bottom line is: it costs less.
