Distribution transformer
A distribution transformer (or service transformer) is the final step-down transformer in an electrical grid, converting medium voltage (e.g., 11kV or 33kV) to low voltage (e.g., 230V or 415V) suitable for end-users. These 98-99% efficient devices are usually pole-mounted or pad-mounted to supply power to homes, businesses, and commercial buildings. #education video
