Transformer
An electrical device that transfers electrical energy between circuits by changing voltage levels.
Full Definition
A Transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction, typically changing voltage levels. Transformers step up voltage for transmission or step down voltage for building distribution. In buildings, transformers convert utility voltage to usable building voltage (e.g., 480V to 120/208V). They are critical for electrical distribution and are monitored for load, temperature, and maintenance.
