power transformer
Grid voltage changer
A power transformer is a device that transfers electrical energy between circuits, typically changing voltage levels—stepping up for long-distance transmission or stepping down for household use.
These large, often oil-cooled units are the workhorses of electrical grids, found at substations and utility poles: The lightning strike fried the neighborhood's power transformer.
