Ülekandevõrgus

Ülekandevõrgus is an Estonian term that translates to "transmission network" in English. It refers to the infrastructure responsible for transporting electrical energy from power generation facilities to consumers. This network is a critical component of any modern electrical system, ensuring the reliable and efficient delivery of electricity.

The transmission network typically consists of high-voltage power lines, substations, and transformers. High-voltage lines are used to minimize energy loss over long distances. Substations play a vital role in stepping down the voltage from transmission levels to distribution levels, making it safe and usable for end-users. Transformers are essential devices within substations that change the voltage of electricity.

In Estonia, the transmission network is managed by Elering AS, the independent transmission system operator. Elering is responsible for maintaining the physical infrastructure, ensuring its operational stability, and guaranteeing the security of electricity supply throughout the country. They also manage the cross-border connections to neighboring countries' transmission networks, facilitating electricity trade and enhancing regional energy security. The efficient functioning of the ülekandevõrgus is crucial for the economy, public services, and daily life, supporting everything from industrial operations to residential power needs.
