A transformer is an electrical device that is used in AC power distribution systems to safely “step up” or “step down” voltages to meet the incoming power requirements of connected equipment. Transformers achieve this goal without modifying the frequency or amount of electrical power to help ensure connected devices can operate reliably.
There are two primary types of transformers that are defined by the insulation used within the enclosure: dry-type and liquid-filled.
Unlike their liquid-filled counterparts, dry-type transformers do not incorporate oil, silicone or liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils within a dry-type transformer are constructed of a gaseous or dry insulation medium.
The dry type transformer is of two types. They are cast resin dry type transformer (CRT) and vacuum pressure impregnated transformer (VPI). On this page, we will explore the basics of Lingfran VPI low voltage dry type transformers and their most common configurations.
