Transformers have been around for almost two hundred years. The technology began with the discovery of electromagnetic induction by the English scientist Michael Faraday in the 1830s. (Other scientists probably discovered it around the same time, as well.) Induction is the phenomenon in which a changing magnetic field (magnetic flux) creates a current in a nearby wire. An electrical transformer uses this phenomenon to convert one voltage to another. Since the 1800s, inventors have been making better and better transformers. Today, transformers are crucial components of our electronics as well as our electrical grids.
When choosing a transformer, the top concern is picking the right one for your application. Small transformers come in a variety of sizes and configurations and are suited for electronics or other devices. Large transformers, on the other hand, are capable of connecting you (your building, your campus, etc.) to the power grid. Let’s review some of the considerations when choosing a transformer.
No matter the size of the transformer, a few factors are key in determining which the best fit is. Understanding these factors—and weighing which are the most important to your project—will ensure long-term success, safety, and savings.
