    What makes for a quality single phase transformer?

    As some of the most common transformers used today, single phase transformers are used across a number of applications to step down or step up the operating voltage to a safe and usable level. They only increase or decrease the voltage on the primary winding.

    The most common use for single phase transformers is to allow for safe usage of plug-in electronics. Their advantages include less maintenance, smaller size, and high efficiency. Single phase transformers also have the advantage of being combined and connected together for use in three phase transformer applications if necessary.

    Single phase transformers for multiple uses.

    Buck boost transformers, dry type transformers, oil and liquid filled, low and medium voltage - You name it. Single phase transformers come in a variety of different types and designs and are most often used in the commercial sector for lower voltage applications, though they can also be used in residential dwellings as well.
