A transformer is an electrical device that increases or decreases the voltage and current being dispersed. A transformer is used to increase or decrease the current transferred so that it can operate at the appropriate voltage safely and efficiently.

What is a transformer?

Types of Commercial Transformers

Liquid-Filled Transformers These are used in a wide variety of industrial and commercial locations. They can be used in indoor locations or outdoor locations depending upon the type of fluid they are filled with. They are filled with mineral oil when used outdoors and high fire point fluids when used indoors. Dry-Type Transformers These transformers offer a wide range of industrial functions. Dry-type transformers can be installed in close proximity to the electrical load, so expensive cable runs are not necessary. This type of transformer is cost efficient because they have low operating and maintenance costs. Cast Coil Transformers These transformers have a high dielectric strength and can handle over voltages, electrical stress and thermal stress well. In addition, these transformers generally have a long life and require little maintenance. Due to the cast coil windings moisture and airborne contaminants do not effect the transformer. These transformers are good in facilities like: food and beverage production, pharmaceutical production, automotive production, medical production, and pulp and paper production. Step-up & Step-down Transformers These transformers either increase or decrease the amount of voltage transferred. Pad Mounted Transformers These transformers can be used for underground power distribution systems. Pad mounted transformers are fairly flexible and because of their contemporary design they are comparatively low profile. In addition, you don’t have to place a protective barrier around these units because of their insulated construction. These transformers are good for places like schools, offices, restaurants or retail spaces. Isolation Transformers This type of transformer allows two appliances to be connected without power being directly fed from one device to the other. These types of transformers are usually employed in situations where it is safer to isolate a piece of equipment from the source of power. Toroidal Transformers These transformers are unique because they transfer electricity from one circuit to another without changing the frequency. Toroidal transformers use electromagnetic induction to reduce losses, physical size and weight of switch-mode power supplies. The circular formation they take minimizes the length of wire needed and helps to prevent electromagnetic interference. Custom Transformers These transformers can be designed to meet the size and performance requirements of your electrical system. Buck Boost Transformers These transformers are good for bucking (decreasing) or boosting (increasing) small voltage amounts for lighting applications.
