A device that changes electrical voltage from one level to another, allowing utility power to be used safely in buildings.
An electrical device that transfers energy between circuits through electromagnetic induction, typically to change voltage levels. Step-down transformers reduce voltage for use in buildings (e.g., 13,800V utility to 480V distribution); step-up transformers increase voltage. Transformers are rated in kilovolt-amperes (kVA) and are essential in power distribution systems.
The project required a 500 kVA pad-mounted transformer to step utility power from 12,470V down to 480/277V for the building.
