LV (600V) Dry-Type Transformers - Federal Pacific

1 LV (600V) Dry-Type Transformers Industrial Control Encapsulated 600 Volt Class Ventilated 600 Volt Class DOE 2016 Efficiency Compliant 2 Federal Pacific HistoryIn 1987, Electro-Mechanical acquired the Dry-Type transformer division of Federal Pacific Electric in Des Plaines, Illinois. It was moved to Bristol, Virginia and the name was changed to Federal Pacific (FP). A new 100,000 square foot facility was constructed where time-proven designs and modern technology were combined and deployed under new management. Expansion in early 1993 provided an additional 36,000 square feet of manufacturing Pacific TodayFederal Pacific is a major manufacturer of Dry-Type Transformers which serve the industrial, construction, commercial, mining, OEM and utility markets.

9 A trans-former links together two or more electrical circuits through the process of electromagnetic induction. A simple transformer consists of two coils of electrical wire wrapped around a common closed magnetic iron circuit (or core ). The coils are electrically isolated from one another but magnetically linked through the core, allow-ing electrical power to be transferred from one coil to the are primarily used to increase ( step-up ) or decrease ( step-down ) voltage from their input ( primary ) to their output ( secondary ). The amount of voltage change is determined by the ratio of the number of turns in the primary coil to the number of turns in the secondary coil.

10 A secondary use of Transformers is to electrically isolate the input from the output circuit while maintain-ing the same input and output Shielded TransformersElectrostatically shielded Transformers are designed to protect primary systems from unwanted high-frequency signals gener-ated by loads connected to a transformer s secondary. While all Transformers with separate primary and secondary windings provide some isolation from load circuits, transients and electrical noise can be transmitted through the internal capacitance of the transformer windings. These disturbances may have a detrimental effect on sensitive electronic equipment and can cause improper operation.
