Answer: The fundamental difference lies in their purpose, voltage levels, and scale. power transmission is the bulk movement of electricity from large-scale power plants to distant substations. It operates at very high voltages (typically 110 kV and above) to minimize energy loss over long distances. Power distribution, on the other hand, is the final stage of delivering electricity from these substations to individual homes, businesses, and industrial customers. It uses lower, stepped-down voltages (typically below 33 kV) for safe and practical use.
