korkeajänniteverkoille

Korkeajänniteverkoille refers to high-voltage electricity transmission networks in Finland. These networks are essential for transporting large amounts of electricity from power generation plants to areas where it is consumed, such as cities and industrial centers. The Finnish high-voltage grid operates at voltages typically ranging from 110 kilovolts (kV) to 400 kV, and in some cases even higher.

The primary purpose of these high-voltage lines is to minimize energy loss during long-distance transmission. By stepping up the voltage, the current can be reduced, which in turn significantly lowers the resistive losses in the power lines. Before electricity reaches consumers, the voltage is stepped down through a series of substations to lower levels suitable for distribution within local areas and finally to household use.

The Finnish high-voltage network is managed by Fingrid Oyj, which is responsible for its planning, construction, operation, and maintenance. Fingrid ensures the stability and reliability of the electricity supply across the country. The network is interconnected with neighboring countries' grids, facilitating electricity trade and enhancing the overall security of supply. Maintenance and upgrades of these extensive networks are crucial for preventing outages and ensuring the efficient flow of electricity.
