Transformers are important parts of most commercial electrical systems and a part that’s unfamiliar to many people because they’re rarely part of home electrical systems. The job of a transformer is to raise and lower voltage levels for a facility as necessary, and without a change in the electrical frequency (which is the job of an alternator) and only work with AC (alternating current). Essentially, transformers are electrical regulators and are have a variety of uses.
If your business relies on one or more transformers, you can expect these devices to last for many years—provided they were accurately installed. Transformers do not contain any moving parts, which accounts for their longevity. However, we have to emphasize how important it is that you only allow licensed commercial/industrial electricians to handle installing a transformer when you need one. We’ll explain why below.
