pohjakaapelin

Pohjakaapeli is a Finnish term referring to a substation or a primary substation that provides power to a grid or an area. It is an essential part of the electrical power distribution system, serving as a node that connects several feeders or power lines together.

The primary function of a pohjakaapeli is to take electric power from the transmission grid and distribute it to various distribution substations or directly to consumers. This local substation is typically equipped with large power transformers, switchgear, and other equipment necessary for controlling and regulating the flow of electricity.

A pohjakaapeli is also responsible for stepping down the high voltage from the transmission grid to a lower voltage suitable for distribution. It often includes intermediate substations that operate at lower voltage levels than the primary substation. The equipment and infrastructure of the pohjakaapeli are designed to handle the power requirements of a specific area.

In Finland, pohjakaapeli are typically owned and operated by the public utility companies. Regular maintenance and inspection of these electrical substations are essential to ensure reliable and efficient power distribution, especially considering the country's vast and sparsely populated areas.

The infrastructure requirements for pohjakaapeli include remote accessibility and the use of automation to monitor and control the electrical flow. As a result, modern substation designs often integrate information and communication technology to allow for remote monitoring and troubleshooting.
