lähetysverkon

Läheitysverkko, known in English as a transmission network, refers to the system of high-voltage electrical power lines and associated infrastructure responsible for transmitting electrical energy from power generation plants to distribution substations. This network forms a critical component of the electrical power system, enabling efficient and reliable energy delivery across large geographical areas.

The primary function of a lähetysverkko is to transport bulk electricity over long distances with minimal losses. It operates at high voltages, typically ranging from 110 kV to 400 kV, which reduces current and thereby decreases energy dissipation as heat. High-voltage transmission lines are often supported by pylons or towers and are designed to withstand environmental factors such as weather and wind.

Lähetysverkko is operated and maintained by transmission system operators (TSOs), which are responsible for ensuring stability, security, and balance within the network. This involves monitoring system conditions, managing power flows, and coordinating with generation and distribution entities. The network's reliability is vital for maintaining a continuous supply of electricity, preventing blackouts, and facilitating scheduled maintenance or emergency responses.

In addition to its technical function, lähetysverkko plays a role in integrating renewable energy sources, such as wind and solar power, by transmitting distributed generation to consumption centers. As the energy landscape evolves toward more sustainable sources, the capacity and flexibility of transmission networks are increasingly emphasized.

Overall, the lähetysverkko is a fundamental element of modern electrical infrastructure, supporting economic activity and daily life by ensuring the steady and efficient supply of electrical power.
