Power Transmission and Distribution

Transmission: This refers to the transportation of high-voltage electricity from power stations to substations, typically over long distances through transmission lines. The voltage is increased (step-up) for efficient long-distance travel, and then stepped down at substations to safer, usable levels.

Distribution: This is the process where electricity is further delivered from the substations to the final consumers. The voltage is reduced (step-down) to levels suitable for residential, commercial, and industrial use.
