Electric power transmission - Wikipedia
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network.

Utility Power Transmission and Distribution Systems
2021年10月16日 — A utility power transmission and distribution system consists of transmission substations (step-up trans-formers), transmission lines, distribution substations (step-down transformers), and distribution lines.
The Transmission Substation - How Power Grids Work - HowStuffWorks
The three-phase power leaves the generator and enters a transmission substation at the power plant. This substation uses large transformers to convert or "step up" the generator's voltage to extremely high voltages for long-distance transmission on the transmission grid.
Electricity transmission networks are designed to minimize power loss over long distances by transmitting power at high voltage. Power plants generally produce electricity at low voltages (5– 34.5 kilovolts (kV)). “Step up” substations are used to increase the voltage of generated power to allow for transmission over long distances.

The lines network between Generating Station (Power Station) and consumer of electric power can be divided into two parts. We can explore these systems in more categories such as primary transmission and secondary transmission as well as primary distribution and …
Transmission Lines and Substation Types - Electrical Academia
There are several types of electrical substations, each connecting two or more elements in the power transmission system. A Step-up Substation connects the power generating plant to the transmission lines.
