What do street lamps, large motors, data centers, and stadiums have in common? They all rely on ready access to electricity—and lots of it.
But getting electricity for a specific purpose isn't as simple as hooking up directly to the power lines. The high voltage electricity in power lines is only suitable for transmitting power over long distances. To be usable in everyday applications, the electricity must pass through a transformer which converts the power to a suitable voltage.
Many people know what a transformer looks like. Understanding how they work, though, is a different story. Whether you're budgeting for a transformer or installing one, knowing what transformers do and how they work provides greater clarity on what you need. In this article, you'll find an introduction to transformers, why we need them, how they work, and a run-through of their most important parts.
In the simplest of terms, a transformer is an electrical device that takes a given input voltage and changes it to a different output voltage. This change can either be an increase or a decrease in voltage.
