Power transmission is the process of delivering electrical energy from power plants to end-users through a network of high-voltage transmission lines and substations. This crucial stage in the energy supply chain involves converting electricity generated at power stations into high-voltage currents to minimize energy loss over long distances.

The electricity is then stepped down to lower voltages by substations before reaching homes, businesses, and industries. Efficient power transmission relies on robust infrastructure and advanced technology to manage and control the flow of electricity, ensuring stability and reliability in the power grid.

Modern systems incorporate smart grid technology to enhance performance and address challenges such as fluctuating demand and integrating renewable energy sources.
